Hi, Team:

My customer is using TPS3813Q now but meet an issue when doing the program upgrade or in debug status.

When doing program upgrade or in debug status, the MCU can’t output right signal to TPS3813 that makes TPS3813 output reset signal to MCU.

 

I think watch dog should be disabled in program upgrade or in debug status. But I checked and even can’t find right watchdog reset IC with enable.

 

Can you help to check if we have suitable watch dog IC with enable similar as TPS3813 and how other customer use TPS3813 to prevent such issue?

 

BTW, it's for automotive application and AEC-Q100 version will be needed.
