HA16113FPJ
Dual Watchdog Timers
The HA16113FPJ is a multifunction device that provides microprocessor systems with the necessary
regulated power supply, monitors the supply voltage, and generates power-on reset and watchdog reset
signals. It is ideally suited for battery-operated systems such as instrumentation systems.
Functions
• Regulated power supply
• Power-on reset
• Two built-in auto-reset circuits
• Two built-in watchdog timer circuits (WDT)
• Output voltage monitoring (LVI)
Features
• Simultaneous or independent control of auto-reset outputs.
• Precisely regulated output voltage and accurate NMI trigger voltage (both ±2%).
• Low-voltage control with NMI, simultaneous RES1 and RES2, and STBY outputs.
• Independently selectable durations for power-on reset and auto-reset: power-on duration is common to
both reset outputs; auto-reset durations can be selected independently.
• Reset command input pin (CONT) for second reset output (RES2).
• WDT filter function detects minimum pulse width and maximum period of P-RUN input pulses.
