Hi Cooper,

Thank you for your question, aside for time delay and watchdog, do you have any other requirement for the device? Also What kind of watchdog are you looking for? Window or time out? Also do you need watchdog + supervisor or just watchdog?

Hi Cooper,

Currently at the moment, we only have the TPS3431, TPS3430, TPS3851, and TPS3850.

https://www.ti.com/product/TPS3431

https://www.ti.com/product/TPS3430

https://www.ti.com/product/TPS3851

https://www.ti.com/product/TPS3850

These devices have a programmable delay time, using a capacitor, but the highest it can go is 3.2seconds.
