TPL5010-Q1: How to deal with DONE pin if watchdog is not utilized?

Part Number: TPL5010-Q1

Hi team,

I have a question regarding TPL5010-Q1.

If I only utilize the timer function of TPL5010-Q1, don't use the watchdog function, what to do with the DONE pin? Will I still need input logic signal to this pin or leave it floated is ok?



  • Hi Xiaoying,

    If you do not provide a DONE signal, you won't have the WAKE signal, but the RSTn pin will toggle every tIP as set by the external resistor on the DELAY pin.

    I suggest shunt the DONE pin to ground via a small resistor (say, 1kΩ).
