Hi team,
DRV8424PPWPR is used for driving DC Brushed motor in PWM mode.
But the motor can only be turned forward, not reversed.
IN1=1 IN2=0 IS WORK OK
IN1=0 IN2=1 IS BAD
The CPU program uses the simplest level control in1=1,in2=0 forward rotation. and for out1,2 oscilloscopes observe square waves. When in1=0,in2=1. Don't move. out1,2 oscilloscope observation no square wave, is clutter, indicating that there is no output signal at this time.
Both A and B drivers do this.
The circuit PCB completely refers to the manual.
Could you help check this case? Thanks.
Best Regards,
Cherry
