The MP6612 from Monolithic Power Systems is a Half-Bridge DC Motor Driver that is used for driving reversible motors. It requires an input voltage of 4-45 V for operation and has an output current of up to 5 A. The motor driver consists of four N-channel power MOSFETs and an internal charge pump that generates the gate driver voltages. . It offers low quiescent current (IQ) in brake mode while two LS-FETs are on configurable current limit.

Features & Benefits

  • Wide 4V to 45V Operating Input Voltage (VIN) Range
  • Internal Full H-Bridge Driver Supports 100% Duty Cycle with Internal Charge Pump
  • Current Sense with 10% Accuracy
  • 5A Continuous Output Current (IOUT)
  • Low On Resistance:
    • 70mΩ High-Side MOSFET (HS-FET)
    • 45mΩ Low-Side MOSFET (LS-FET)
  • Cycle-by-Cycle Current Regulation/Limiting
  • IN1 and IN2 Logic Inputs
  • Low Quiescent Current (IQ) in Brake Mode while Two LS-FETs are On
  • Configurable Current Limit
  • Over-Current Protection (OCP)
  • Over-Voltage Protection (OVP)
  • Over-Temperature Protection (OTP)
  • Fault Indication for OCP, OVP, and OTP
  • Available in a TSSOP-20 EP Package with an Exposed Thermal Pad

The MP6612 supports a 100% duty cycle with an internal charge pump and has a current sensing feature with 10% accuracy. It is integrated with over-current protection (OCP), over-voltage protection (OVP), under-voltage lockout (UVLO) protection, and over-temperature protection circuitries. The motor driver is available in a surface-mount package and is ideal for driving DC motor, stepper motor winding, and other loads.
