I would like to use a watchdog timer as a way to do a proper power cycle in last resort, that is: power down for 1 second, then power up. I have come up with the following design:
The watchdog used here is a MAX6746, the load switch is a FDC6330. +5V_DCIN is plugged to a 5V DC, +5V goes to the rest of the circuit. The capacitors set the timers at 1s active reset, 30s watchdog timeout.
The problem is it is stuck in a loop where every 1s the FDC6330 enables the power to +5V then instantly back to 0V. Any idea? I could not find such use cases on google, watchdogs are usually used to directly control a reset pin for a mcu.
