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.
