BLDC Motor and DC Brushed Motor Driver

BLDC Motor and DC Brushed Motor Driver


This BLDC motor driver board is equipped with a smart IFX007T half-bridge. The BLDC motor control project is capable to drive one BLDC motor. Alternatively, it can be used to drive one or two bi-directional DC motors (H-Bridge configuration, cascaded to support the second motor) or up to three uni-directional DC motors (half-bridge configuration). The implemented integrated IFX007T half-bridges can be controlled by a PWM via the IN Pin. Interfacing to a microcontroller or Arduino is easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, and dead time generation, etc. The three IFX007T half-bridges are also fully protected against over-temperature, under-voltage, overcurrent, and short circuit events. The project is capable of high-frequency PWM e.g., 30Khz. All inputs are logic level, current sense outputs are for diagnosis purposes, and slew rates are adjustable using R7, R8, R9. This is able to be used for fast and inexpensive prototyping of (BL)DC motor control, easy testing of half-and full-bridge motor control Status flag diagnosis with current sense capability, Over-temperature shut down with latch behavior and under-voltage shut down. It is advisable to use forced cool air to control the temperature of the IFX007 chip.
