Dear Members.

I am controlling motor uing drv8833.

I implemented forward and reverse control using PWM and it works well few days.

But suddenly it stops working and the problem is nFault pin is driven LOW as soon as starting PWM signal.

There is no load on Motor so overcurrent cannot happen there.

Please help me what is going on there

Dear Piaozhun,

Were you able to confirm what type fault occurred? You can use observe the nFAULT pin and determine what fault occurred using Table 3 in the datasheet.
