Hi All,

How do I reset assert of nFAULT on the DRV8353?

The datasheet states how to reset it in 8.4.1.3 Fault Reset (CLR_FLT or ENABLE Reset Pulse).

Are there any other reset methods?

Hi Ishiwata,

The only two ways to reset the fault status is in the section you referenced: 8.4.1.3 Fault Reset (CLR_FLT or ENABLE Reset Pulse)

Is there a reason you were looking for a different way to reset fault?

Yara

Hi Yara,

The reason I asked the question is because there is a timing when the fault is cleared when a PWM signal is input.
Will the fault be cleared by the PWM input?

Hi Ishiwata,

I believe the two methods listed in the datasheet are the only way to clear faults, a PWM signal on the input pins will not clear the fault.
