DRV8243-Q1: DRV8243HQRXYRQ1 Not working nFault is "0"

Thanks Jacob for the replay,

I have connected the nSLEEP to the microcontroller and apply 2ms '0' pulses after 500ms from power up ().

but steel the driver not wakeup is it wrong timing ? 

i will check if return the nFault signal to microcontroller and rise the nSLEEP immediate as nFault rise will help. 

Can i do the sequences without sampling the nFAULT ?

is and way to apply the wakeup sequences using hardware (capacitors etc') ?

Thanks,

Ofer 

Hey Ofer,

The reset pulse on nSLEEP needs to be between 5us and 20us long:

I don't know of a way to implement this with hardware, but I think the correct RC filter would likely be able to apply a 5-20us pulse

Best,

Jacob

Thanks a lot Jacob it's working after reducing the nSLEEP pulse size to 5us.
