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 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 (4.63V,
Typ) or the
STBY
detection voltage (3.0V Typ), this function outputs either an
NMI
signal or an
STBY
signal, respectively. Note that NMI detection can be set to monitor either V
CC
or 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.
