Hi,

Customer is driving HRESET using their EC GPIO. What is the minimum timing they should drive HRESET low to make it work? Do we have any suggested timing here? Or it's simply falling edge triggered?

Thanks!

Hi Antony,

The HRESET pin is edge driven on a rising edge. I would suggest recommending a ~1mS high signal when they would like to trigger HRESET. As soon as the HRESET signal returns to 0, the TPS65988 will start the reset sequence.

Thanks,
Eric
