Hi team,
The customer uses DRV8842 to drive a 24V/2A DC motor. His schematic is in the attach.
The I0 pin is connected to MCU. The ISEN pins are shorted to GND. The V3PVOUT pin is connected to VREF pins.
The 7.3.3 Current Regulation of the datasheet shows this information and it is correct. The nFault pin is the high level.
The 29 pin that is the PPAD is floating.
When the input signals are input to IN1 pin and IN2 pin, but there is no any output signal.
Would you check the customer's schematic and provide some suggestions for the customer's issue?
Best Wishes,
