Hi expert,
My customer wants to search for reset IC for their router application. CPU will assert a GPIO for reset and they want to cut off adapter power to system through a MOSFET under-controlled. After certain time period(2 seconds or longer), RESET will be de-asserted automatically then main switch will turn on again, adapter can power system again. I found that TPS3852 has watchdog feature, does programmable watchdog timer could support this application?
Condition : 19Vin, GPIO from CPU but only one shot since we would turn off main switch to disconnect system to adapter.
Best regards,
Ann Lien
