TPS4H160-Q1: Toggle Duration to Reset Fault after Thermal Shutdown

Hi team,

After thermal shutdown occurs, toggling INx pin can clear the fault - what is the duration requirement? Maybe the deglitch time for INx from high to low, whcih is 12.5ms (typ)?

Thanks.

    Hi Pengyu,

    Thanks for reaching out on E2E!

    You are correct. The time it takes to clear a thermal shutdown fault by toggling the INx pin consists of the time it takes to switch it from high to low and then from low to high. Since the IN pin can go from low to high almost instantly, we can  say the duration would be 12.5ms (typ) with a minimum of 10ms and maximum of 15 ms.

    Best Regards,

    Elizabeth
