DRV8350R: Motor running without PWM

Part Number: DRV8350R


Tool/software:

Hi,

I am using DRV8350RS in 1x mode, initially everything was fine. Motor was running when I feed PWM pulse. Suddenly, motor start running without feeding PWM. I checked the PWM pin of DRV, 3v3 is appearing when this pin is not connected with MCU and there is no assembly issue. This is the serious problem I found.

Please help, what can be the problem?

Thanks in advance,
