DRV8302: Unknown Fault

$
0
0

Part Number:DRV8302

I am using the DRV8302 driver, it works fine normally but some times after quick changes of the PWM duty cycle the output gate drivers stop driving. The fault  the OCTW pin are both still high. I can clear the error by cycling the EN_GATE pin. I cannot find any situation in the datasheet that meets this criteria. All the faults that can be cleared by toggling the EN_GATE pin should set the ~FAULT or ~OCTW pin. 

Is there a rare situation where this is not the case?

Thank you,
