Part Number: TPS1HC30-Q1

Hi team, 

How is its nFAULT cleard (Hi-Z) from OCP event? DIAG_EN pin is high and Latch pin is floating. 

Are the only way clear nFAULT "pull down EN" or "overcurrent condition is released"?

Regards,
Ochi

    Hi Ochi-san,

    Yes you are correct that pull down "EN" which shuts off the part, or the overcurrent condition is released will be two ways to clear the fault. Also pull DIAG_EN low will release the FAULT as well.

    Please let me know if you have additional questions.

    Regards,
