I'm designing an MCU interface between a PIC18F67J11 (3.3v) and a DRV8832. My motor is a 6V DC brushed motor. I want to use the iSense capability to limit current to 400 or 500mA. I do not need variable speed control. The system requires forward/reverse and braking. Do I need to plan for cycling the power to the DRV8832 in the event of an OCP fault or does the iSense limit prevent them from happening?
I have ordered the DRV8832EVM, but I don't understand the use of Vset and Vref. I would like to run the motor with logic levels applied to IN1 and IN2 only. Is this possible?
