TPS1641: Behavior on Short to GND

Oba

Part Number: TPS1641

Hello,

I want to confirm the behavior on "Short go GND" case (I_SCP) of TPS1641

From the Figure8-14 on the datasheet, FLT stays on HIGH status after short event.
Doesn't FLT go to LOW whne I_SCP occurs?

And how to recover from this condition?
Auto-reply or latch-off depending on the part number?

Regards,
Oba

    Hi Oba,

    FLT will not go low during short at output.

    After fast-trip irrelevant of latch-off or auto-retry device will try to start again. Actually above waveform is at zoomed in scale so we are not seeing that. 

    Regards
