Hola,

Does TI have watchdog IC which can generate low for long time (> 1sec) and pin to pin to TPS3813 (SOT23)？

Thank you

Hi Jacky,

At this time, no we do not. However, we do have a solution to block the WD with the TPS3306:

The TPS3306 will disable the Watchdog timer if the WDI input is floating.This is not possible with the TPS3813.

I hope this helps

Hola John,

Just confirm with you that the circuit block diagram of TPS3306 which you recommended can be achieved generate low for long time (> 1sec)？
