ESP32 startup time and external watchdog

[jimhelios]

Hi, I'm working on a circuit that will use an ESP32-WROOM-32U and I'm thinking that an external watchdog is a good idea. However, I'm aware that the ESP32 starts very slowly, so I was looking at the TSP3823 which has a startup delay of 1.6 seconds after VDD exceeds 1.1V. Is this sufficient? Is there anything else I should be concerned about, such as debugging or OTA updates?

Thanks...
