TPL5100: TPL5100 as a watchdog

TPL5100: Counter Reset

Hi 

We observed that the DRV signal of TLV5100 still comes even if DONE  signal is provided. 

Does the counter in TLV5100 reset after DONE  signal is provided and the DRV counter starts counting again?

What is the effect of DONE signal on DRV signal?

Regards,

Prashant

    Hi Prashant,

    DRV always toggles at the end of period.  If DONE is asserted, DRV will toggle earlier.  DONE does not stop and/or clear the timer, it stops DRV ahead of the expiration of the timer.  The timer is always active and counting.

    If you don't want DRV to toggle, then perhaps you should consider a watchdog timer like the TPL5000.

    Best Regards,
