TPS3813-Q1: Reset pin issues for TPS3813-Q1

Part Number: TPS3813-Q1

Hi TI expert

If the WDI signal remains at a fixed level, the reset pin will output a reset signal and the high level will not change? Or according to the internal timer setting, output reset signal regularly?

Best regards,


  • Hi Thomas,

    The TPS3813-Q1 is a watchdog window where the WDI needs to occur between the lower and upper boundary.  If the WDI does not occur within the window, the reset pin will be asserted.  See below:

    To answer your question, the output will reset regularly.

    I hope that I have answered your question.
