Summary
Single Watchdog Timer
Description
The HA16129FPJ is a watchdog timer IC that monitors a microprocessor for runaway. In addition to the watchdog timer function, the HA16129FPJ also provides a function for supplying a high-precision stabilized power supply to the microprocessor, a power on reset function, a power supply voltage monitoring function, and a fail-safe function that masks the microprocessor outputs if a runaway is detected.
