Hello team,
I have a circuit driving a 2A DC motor with a DRV8842. It works very well and is capable to start the motor without any problems. But *sometimes* (About 50% of the times) when the motor is stopped, I get an overcurrent fault. I think it is the back emf from the that makes the overcurrent protection trigger. Do you have any suggestion what I can do to avoid the OCP getting triggered by the motor back EMF? Is current limiting in the chip a possible solution? Or fading down the motor voltage via PWM instead of switching off instantly?
I'll apreciate your suggestions.
Thank you very much,
Igor
