TPL5010 as 10 Minute Timer

Other Parts Discussed in Thread: TPL5010

Hi,

i need a setup for the TPL5010 as 10 Minute Timer.

I have only 1 Pin on my µC as Interrupt/Wakeup pin.

So After 10 min the Interrupt Pin should go from HIGH to LOW.

    Hi Stephan.

    If you have just one pin available for interrupt and wake up it means that you are not interested to the watchdog feature isn't it ?

    If so you can use the Reset pin of the TPL5010 to wake up your uC. Make sure to connect the DONE pin to GND and leave the WAKE floating . Connect the RESET pin of the TPL5010 to the interrupt pin of your  uC  and do not forget the pull-up resistance.

    In the Datasheet you can find the right value of the external eresistancee to set 10 min.

    Regards Domenico
