HA16129FPJ 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.
Functions • Watchdog timer (WDT) function Monitors the P-RUN signal output by the microprocessor, and issues an auto-reset (RES ) signal if a microprocessor runaway is detected.
• Stabilized power supply Provides power to the microprocessor.
• Power...
