HA16103 FPJ/FPK

Watchdog Timer

Description

The HA16103FPJ/FPK monolithic voltage control is designed for microcomputer systems. In addition to
voltage regulator, it includes watch dog timer function, power on reset function, and output voltage monitor
function.

It is suitable for battery use microcomputer systems.

Functions

• 5 V regulated power supply

• Power on reset pulse generator

• Watch dog timer

• Low voltage inhibit protection

Features

• Wide operational supply voltage range (VCC = 6 to 40 V)

• Various control signals are generated when microcomputer system runaway occurs. (NMI signal and

STBY signal are generated by detecting voltage level, and RES signal is generated by monitoring the
time after NMI signal is detected)

• Regulated voltage, NMI detecting voltage, STBY detecting voltage are adjustable.

• At low voltage and re-start, the delay time of RES signal is adjustable

• Watchdog timer filtering uses the minimum clock input pulse width and maximum cycle detection

Functional Description

Stabilized Power Supply Function

The stabilized power supply includes the following features:

• Wide range of operating input voltage from 6 V to 40 V to provide stabilized voltages

• Availability of any output current, by simply replacing the external transistor

• Fine adjustment of output voltage

Figure 1 shows the fine adjustment circuit of the output circuit. Select the resistor R1 as shown in
equation 1.

Add a resistor between GND and Voadj to increase the output voltage.

Watchdog Timer Function

The system contains a bandpass filter for pulse width detection, which outputs a reset pulse when input
pulses are not at the preselected frequency (at either a higher or lower frequency).

The RC characteristic of the bandpass filter may be set with external components Rf and Cf. Equation 3
specifies how to determine the minimum pulse width (tmin) for runaway detection of the bandpass filter,
and figure 4 shows the characteristic of the filter.

Low Voltage Monitoring Function

The system contains a circuit to send a control signal to the microcomputer when the output voltage drops.
The circuit includes the following features.

• Two-point monitoring of output voltage (V

NMI

and V

STBY

)

• Availability of fine adjustment of Vth1 (V

NMI

) and Vth2 (V

STBY

)

• Output of control signal in standby mode of microcomputer

Figure 5 shows the timing chart of control signals when the output voltage drops.

If the output voltage drops below Vth1 (4.60 V), the NMI signal rises to request the microcomputer to issue
the NMI interrupt signal. The RES signal falls t

RES

seconds after the NMI signal rises. If the output voltage
drops further to below Vth2 (3.2 V), the STBY signal rises to enable the micro-computer to enter standby
mode.

Precautions

If the IC’s ground potential varies suddenly by several volts due to wiring impedance (see figure 6), a false
RES pulse may be output. The reason for this is that potentials in the RES pulse generating circuit change
together with the V

OUT

-GND potential. The reference potential of the comparator in figure 7 and the
potential of the external capacitor have different impedances as seen from the comparator, causing a
momentary inversion. The solution is to stabilize the ground potential. Two ways of stabilizing the IC’s
ground line are:

• Separate the IC’s ground line from highcurrent ground lines.

• Increase the capacitance (Co) used to smooth the V

OUT

output.
