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 on and clock off functions

The power on function outputs a low level signal to the microprocessor for a fixed period when power is first

applied.

The clock off function outputs a RES signal to the microprocessor a fixed period after a runaway occurs.

Power supply monitoring function

•

When the reference voltage (Vout) falls and becomes lower than the NMI detection voltage (4.63 V, Typ) or the

STBY detection voltage (3.0 V Typ), this function outputs either an NMI signal or an STBY signal, respectively.

Note that NMI detection can be set to monitor either V_CCor Vout.

OUTE function^*1(fail-safe function)

Outputs a signal used to mask microprocessor outputs when a microprocessor runaway has been detected.

RES delay function

•

Sets the delay between the time the NMI signal is output and the time the RES signal is output.

Protection functions

The HA16129FPJ incorporates both Vout overvoltage prevention and current limiter functions.

Note: 1. OUTE function: OUTE is an abbreviation for output enable.

Features

•

High-precision output voltage: 5.0 V 1.5%

The WDT supports both frequency and duty detection schemes.

High-precision power supply monitoring function: 4.625 V 0.125 V

Built-in OUTE function

All functions can be adjusted with external resistors and/or capacitors.
