Hello,
I am using a TPS3813K33DBVR watchdog chipset on one our project and I have a strange behaviour.
I connected WDR to GND and WDT to 3.3V. According to the datasheet, that means I have a 3 s window to send a pulse to WDI to not have a reset .
However, after power up, I send a pulse after 1s and the watchdog reset 100ms after (see picture).
can you explain me why a reset occurs even if I have a pulse.
Thanks
Regards,
