Two Channel High Side Driver with Analog Sense for Automotive Applications

The project presented here is suitable for all types of resistive, inductive, and capacitive loads, and can also be used to drive LEDs. The board is built using 2 x VN5025AJ chips which are monolithic devices made using STMicroelectronics VIPower technology. It is intended for driving resistive or inductive loads with one side connected to the ground. Active VCC pin voltage clamp protects the device against low energy spikes. This device integrates an analog current sense which delivers a current proportional to the load current (according to a known ratio) when CS_DIS is driven low or left open. When CS_DIS is driven high, the CURRENT SENSE pin is in a high impedance condition. Output current limitation protects the device in overload conditions. In case of long overload duration, the device limits the dissipated power to a safe level up to thermal shut-down intervention. Thermal shut-down with automatic restart allows the device to recover normal operation as soon as the fault condition disappears.

Breakout Board for UCC28019 and UCC28128 PFC Controller

This is a breakout board for UCC28019 and UCC28128 PFC controllers. This module enables users to build a high-power PFC (Power Factor Correction) controller. Active PFC uses the boost topology operating in Continuous Conduction Mode (CCM). The controller is suitable for systems in the 100 W to >2 kW range over a wide-range universal ac line input. The startup current during an under-voltage lockout is less than 200 µA. The user can control low-power standby mode by pulling the VSENSE pin below 0.77 V. Low-distortion wave-shaping of the input current using average current mode control is achieved without input line sensing, reducing the Bill of Materials component count. Simple external networks allow for flexible compensation of the current and voltage control loops. The switching frequency is internally fixed and trimmed to better than 5% accuracy at 25°C. Fast 1.5-A gate peak current drives the external switch.

Numerous system-level protection features include peak current limit, soft over-current detection, open-loop detection, input brown-out detection, output over-voltage protection/under-voltage detection, a no-power discharge path on VCOMP, and overload protection on ICOMP. Soft-Start limits boost current during start-up. A trimmed internal reference provides accurate protection thresholds and regulation set-point. An internal clamp limits the gate drive voltage to 12.5 V.

Note 1: The PFC controller module is published here. The second part (mainboard) is 350W Power Factor Boost Converter for Inverter-Fed BLDC and PMSM Motors.
Note 2: This module can accommodate two chips UCC28019 or UCC28180. Refer to the datasheet of both chips to select the components as per requirements.

It combines a flexible ramp generator for automatic target positioning with the industry’s most advanced stepper motor driver. Using external transistors, the driver ensures absolutely noiseless operation combined with maximum efficiency and the best motor torque. High integration, high energy efficiency, and a small form factor enable miniaturized. The complete solution reduces the learning curve to a minimum while giving the best performance in class. The project has the option to interface an external incremental encoder for easy control of position and step-loss operations.

Note 1: Refer to the datasheet of TMC5160 to understand the SPI interface and control system.
Note 2: This board only works with serial-SPI mode, it doesn’t support standalone mode.

Mode of Operation

MODE 1: Full Featured Motion Controller & Driver

All stepper motor logic is completely within the TMC5160. No software is required to control the motor – just provide target positions. Enable this mode by tying low pin SD_MODE. Install Resistor R2 0 Ohms to select this mode. Do not install R1.

MODE 2: Step & Direction Driver

An external high-performance S-ramp motion controller like the TMC4361 or a central CPU generates step & direction signals synchronized to other components like additional motors within the system.  The TMC5160 takes care of intelligent current and mode control and delivers feedback on the state of the motor. The Micro Plyer automatically smoothens motion. Tie SD_MODE high. Install Resistor R1 0 Ohms to select this mode. Do not install R2.

Mode Selection

  • Soldering R2 / not R1 = Internal ramp generator active with Trinamic’s 6-point-ramp (default mode)
  • Soldering R1 / not R2 = Step/Direction interface active for use with external motion controller (STEP =REFL, DIR = REFR)

Automatic Standstill Power Down

An automatic current reduction drastically reduces application power dissipation and cooling requirements. Modify stand still current, delay time and decay via register settings. Automatic freewheeling and passive motor braking are provided as an option for stand still. Passive braking reduces motor standstill power consumption to zero, while still providing effective dampening and braking! An option for faster detection of standstill is provided for both, ramp generator and STEP/DIR operation.

Encoder Interface

TMC5160 board provides an encoder interface for external incremental encoders. The encoder allows automatic checking for step loss and can be used for homing of the motion controller (alternatively to reference switches), or for software-controlled correction of step-loss or position stabilization. Its programmable pre-scaler allows the adaptation of the encoder resolution to the motor resolution. A 32-bit encoder counter is provided.

Key Concepts

The TMC5160 board implements advanced features which are exclusive to TRINAMIC products. These features contribute toward greater precision, greater energy efficiency, higher reliability, smoother motion, and cooler operation in many stepper motor applications.

  • StealthChop2™ No-noise, high-precision chopper algorithm for inaudible motion and inaudible standstill of the motor. Allows faster motor acceleration and deceleration than StealthChop™ and extends StealthChop to low stand still motor currents.
  • SpreadCycle™ High-precision chopper algorithm for highly dynamic motion and absolutely clean current wave. Low noise, low resonance, and low vibration chopper.
  • DcStep™ Load dependent speed control. The motor moves as fast as possible and never loses a step.
  • StallGuard2™ Sensorless stall detection and mechanical load measurement. CoolStep™ Load-adaptive current control reducing energy consumption by as much as 75%.
  • MicroPlyer™ Microstep interpolator for obtaining full 256 microstep smoothness with lower resolution step inputs starting from fullstep

In addition to these performance enhancements, TRINAMIC motor drivers offer safeguards to detect and protect against shorted outputs, output open circuit, overtemperature, and undervoltage conditions for enhancing safety and recovery from equipment malfunctions.

Control Interfaces

The TMC5160 board supports both, an SPI interface and a UART based single wire interface with CRC checking. Additionally, a standalone mode is provided for pure STEP/DIR operation without use of the serial interface. Selection of the actual interface is done via the configuration pins SPI_MODE and SD_MODE, which can be hardwired to GND or VCC_IO depending on the desired interface.

SPI Interface

The SPI interface is a bit-serial interface synchronous to a bus clock. For every bit sent from the bus master to the bus node another bit is sent simultaneously from the node to the master.  Communication between an SPI master and the TMC5160 node always consists of sending one 40-bit command word and receiving one 40-bit status word.

The TMC5160 scores with complete motion controlling features, powerful external MOSFET driver stages, and high-quality current regulation. It offers a versatility that covers a wide spectrum of applications from battery powered high efficiency systems up to embedded applications with 10A or more motor current per coil. The TMC5160 contains the complete intelligence which is required to drive a motor. Receiving target positions, the TMC5160 manages motor movement. Based on TRINAMICs unique features StallGuard2, Cool Step, DC Step, Spread Cycle, and Stealth Chop, it optimizes drive performance. It trades off velocity vs. motor torque, optimizes energy efficiency, smoothness of the drive, and noiselessness. The small form factor of the TMC5160 keeps costs down and allows for miniaturized layouts. Extensive support at the chip, board, and software levels enables rapid design cycles and fast time-to-market with competitive products.  High energy efficiency and reliability deliver cost savings in related systems such as power supplies and cooling.

TMC5160 Datasheet

DC Motor Position Control Using Potentiometer – Arduino Compatible

The project presented here is an Arduino-compatible motor control board. The board consists of an ATMEGA328 microcontroller, LMD18201 H-Bridge, and 2 x potentiometers. This closed-loop servo system provides position control using a feedback potentiometer mounted on the output shaft of the gearbox and provides position control by turning the shaft of the reference potentiometer, the motor-gearbox output shaft follows the reference potentiometer. The project can also be used in other applications that require Arduino-compatible hardware and H-Bridge.

The project requires a special mechanism, where the DC motor’s output shaft is mechanically coupled with the potentiometer shaft using a reduction gear. Approx. reduction ratio 15-50: 1. When the reference pot is turned, the motor shaft follows the position. This will provide a maximum rotation of 270 degrees. Multi-rotation is possible with the help of a multiturn potentiometer.

Arduino Code

Arduino example code is available and the board can be programmed using the CN2 connector, the same connector helps burn the boot-loader to a new ATMEGA328 chip.

Self-Oscillating Full-Bridge Using IRS2453

This is a Self-oscillating full-bridge project built using the IRS2453 chip. This chip incorporates a high-voltage full-bridge gate driver with a front-end oscillator similar to the industry standard CMOS 555 timer. HVIC and latch-immune CMOS technologies enable ruggedized monolithic construction. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Noise immunity is achieved with a low di/dt peak of the gate drivers and with an under-voltage lockout hysteresis greater than 1.5 V. The IRS2453(1)D also includes latched and non-latched shutdown pins.

Load Supply voltage: 90V DC, this is limited due to capacitor voltage C1, C2, and MOSFETs Q1-Q4. The board can support DC supply up to 600V, choose appropriate capacitors and MOSFETs.

Oscillator: Refer to the figure below to choose the right value of C7 and R3 to program the oscillating frequency.

Heatsink: Heatsink and Fan are a must for MOSFETs and to dissipate heat.

Features

  • Power Supply Gate Driver 12V to 15V DC
  • Power Supply 90V Limited by DC Capacitors and MOSFETS (Up to 600V Change Capacitor C1 and C2)
  • Frequency 68Khz, Oscillator frequency can be programmed using CT, RT (C7 and R3)
  • Load Current Up to 5Amps
  • Duty Cycle 50%
  • Micropower Startup
  • Internal Dead Time 1uS
  • 4 x 4 MM Mounting Holes
  • PCB Dimensions 69.22 x 58.90 mm

Application

  • Wireless Charger
  • Low Power DC to AC Inverter
  • Tesla Coil
  • Induction Heater

Under-Voltage Lock-Out Mode (UVLO)

The under-voltage lockout mode (UVLO) is defined as the state the IC is in when VCC is below the turn-on threshold of the IC. The IRS2453(1)D under-voltage lock-out is designed to maintain an ultra-low supply current of e the high and low side output drivers are activated. During under-voltage lock-out mode, the high and low side driver outputs LO1, LO2, HO1, HO2 are all low. With VCC above the VCCUV+ threshold, the IC turns on and the output begin to oscillate.

Normal Operating Mode

Once VCC reaches the start-up threshold VCCUV+, the MOSFET M1 opens, RT increases to approximately VCC (VCC-VRT+) and the external CT capacitor starts charging. Once the CT voltage reaches VCT- (about 1/3 of VCC), established by an internal resistor ladder, LO1 and HO2 turn on with a delay equivalent to the dead time (td). Once the CT voltage reaches VCT+ (approximately 2/3 of VCC), LO1 and HO2 go low, RT goes down to approximately ground (VRT-), the CT capacitor starts discharging and the dead time circuit is activated. At the end of the dead time, LO2 and HO1 go high. Once the CT voltage reaches VCT- , LO2 and HO1 go low, RT goes to high again, the dead time is activated. At the end of the dead time, LO1 and HO2 go high and the cycle starts over again. The frequency is best determined by the graph, Frequency vs. RT, shown below, for different values of CT.

A first-order approximation of the oscillator frequency can also be calculated by the following formula:

f » 1/1.453 x RT x CT

This equation can vary slightly from actual measurements due to internal comparator over- and under-shoot delays

Bootstrap MOSFET The internal bootstrap FET and supply capacitor (CBOOT) comprise the supply voltage for the high-side driver circuitry. The internal bootstrap FET only turns on when the corresponding LO is high. To guarantee that the highside supply is charged up before the first pulse on HO1 and HO2, LO1 and LO2 outputs are both high when CT ramps between zero and 1/3*VCC. LO1 and LO2 are also high when CT is grounded below 1/6*VCC to ensure that the bootstrap capacitor is charged when CT is brought back over 1/3*VCC.

Connections & Other Details

  • CN1: VDD Pin 1 = + Load Supply, Pin 2 = GND
  • CN2: Pin 1,2 = VCC 12to 15V DC, Pin 2,3 = GND
  • D1: Power LED

U1 MAX680 is a single supply to Dual supply converter. This chip provides a symmetric power supply +/-10V to OPAMP U4. A dual supply is required for Sine-Wave output, in the case of higher voltage output, use external dual power supply input through CN4, in this case, don’t install U1 Max680, capacitor C4, and capacitor C1.

OPAMP

The sine-Wave and Tringle-Wave outputs of AD9833 are very low and need amplification, U4 op-amp is provided to amplify the output of AD9833. This Op-Amp requires a dual supply. Output offset can be adjusted using PR4 trimmer potentiometer and gain adjust using potentiometer PR3. 1 to 20, Maximum output swing +/-7V, for higher voltage swing use external dual power supply for the op-amp, in this case, don’t install U1 MAX680.

AD9833

The AD9833 is a low-power, programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in various types of sensing, actuation, and time domain reflectometry (TDR) applications. The output frequency and phase are software-programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits wide: with a 25 MHz clock rate, a resolution of 0.1 Hz can be achieved; with a 1 MHz clock rate, the AD9833 can be tuned to 0.004 Hz resolution.

The AD9833 is written via a 3-wire serial interface. This serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates with a power supply from 2.3 V to 5.5 V. The AD9833 has a power-down function (SLEEP).

DC Electronic Load – 1A

This is a very precise Electronic Load project built using the ultra-Precision, Low-Noise OPAMP MAX44251 from Analog Devices. The project can sink current from a power source. It can be used as test gear for power supplies, chargers, solar panels, batteries, and DC-DC converters. The resistor R11 acts as a shunt, OPAMPs convert current into voltage, 2nd op-amp, and Q1 MOSFET are used to control the load current. A Multi-turn potentiometer helps to adjust the load current in the range of 0 to 1A. The supply voltage is up to 60V DC. The board works with dual supply +/-15V DC and draws a few milli amps. LM317 regulator provides 12V DC top op-amp and LM337 provides regulated -7V supply to op-amp. At full load, MOSFET Q1 produces lots of heat, and a fan and large heatsink on MOSFET will help cool it down. Users may use a current meter in series to load to display the current. Optional onboard Trimmer potentiometer provided in case external potentiometer is not required.
