LM25184-Q1: Internal deglitch filter on EN

Part Number: LM25184-Q1

Hi team, 

My customer would like to know if there's any deglitch filter internal EN pin? There might be some system noise coupling to EN signal, they would like to know if voltage drops to below EN threshold for long than which duration (some us, or tens of us, or more), our device output will respond?

Thank you

Scarlett

    Hi Scarlett, 

    I can't speak on any deglitch filter on the internal EN pin, but there should be some hysteresis where EN has to fall a little bit below the UVLO EN value in order to shut off the device.

    It also may not make a difference if the device is shut off for 10uS depending on the COUT and IOUT of the system.

    Thanks,

    Andrew
