TPS3820-Q1: If the MCU keeps the WDI pin high..

Part Number: TPS3820-Q1

Hi team

If the MCU keeps the WDI pin high, is it happen reset?

I checked reset status when the WDI pin keeps low.

But I didn't see status of reset pin when the WDI pin keeps high.

Thank you

  • Charles,

    If the WDI pin is kept high or low longer than the time-out period, this will trigger a reset. Also, we recommend that you design the TPS3820-33QPDBVRQ1 and TPS3820-50QPDBVRQ1 for any new designs as it is the same device but we are in the process of switching to a newer part.

    Thanks,
    Abhinav.
