I am using TPL5100 as a watchdog. I have configured D0,D1,D2 as high so I have 1024s timer. Currently, my application is sending DONE pulse (High->Low) every 20 seconds and I expect after 1024 sec, it will not set RSTn pin. In my case, irrespective of DONE signal, after 1024s out HW is getting reseted due to TPL5100.
Can you provide more details how we can implement watchdog using TPL5100.
Update: We have TPL5000 as well and with the same implementation, we are not seeing reset signal and watchdog functionality works fine with it.
So what needs to be change for TPL5100?
Hi Rob,
Thank you for your response.
We are sending DONE(ON->1sec period->OFF) signal every 10 second.
We have HW in which we can use both one by connecting different resistor value.
Below is the schematic of the connection of our HW with TPL5100,
Hi Rob,
Thank you for your response. Now I understand it better. in TPL5100, once DRV signal receive we need to give DONE signal. And in TPL5000, RSTn signal can be reset as soon as we provide DONE signal. So TPL5000 can works as watchdog.
And for sorry confusing with RSTn. I meant to DRV for 5100 and RSTn for 5000.
One more question, our requirement is to have more than 5 minutes timeout and with TPL5000, we can have maximum 64s timeout. Can you please suggest IC which can be used the same as TPL5000 but with more timeout?
Also will TPL5010 or TPL5110 can work in our use-case?
