Description

The HA16129AFPJ is a watchdog timer IC that monitors a microprocessor for runaway. In addition to the watchdog

timer function, the HA16129AFPJ 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 HA16129AFPJ incorporates both Vout overvoltage prevention and short detection 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.
