[FAQ] TPL5010: How to disable the watchdog function of TPL5010

Part Number: TPL5010

Hi all,

I am a FAE of TI,now my customer has a watchdog disabled problem, so I synchronously ask you for a solution:

Problem Description: the customer's MCU wants to disable the watchdog function during the recording program to prevent the MCU from continuously resetting.

What attempts have we made at present: 1. Let MCU continuously send signals to the done pin of TPL5010 (but TPL5010 can only recognize a done signal, so it can not solve the problem); 2. Pull pin 3 (DELAY / M_RST) to VDD, but RST pin will always output low level, which will affect MCU reset.

Schematic diagram of the customer:

My requirement: is there a way to solve the problem of tpl5010 watchdog disabling during MCU program burning (without using wiring cap).
