MB3773
■
DESCRIPTION
The Fujitsu MB3773 is designed to monitor the voltage level of a power supply (+5V or an
arbitrary voltage) in a microprocessor circuit, memory board in a large-size computer, for
example. The MB3773 also contains a watch-dog timer function to detect uncontrol. Table
status of processor and reset system/processor.
If the circuit’s power supply deviates more than a specified amount, then the MB3773
generates a reset signal to the microprocessor. Thus, the computer data is protected from
accidental erasure.
When the MB3773 does not receive the clock pulse from the processor in the specified
period, the MB3773 generates a reset signal to the mciroprocessor.
PLASTIC PACKAGE
DIP-8P-M01
Using the MB3773 requires few external components. To monitor only a +5 volt supply,
the MB3773 requires the connection of one external capacitor.
The MB3773 is available in an 8-pin Dual In-Line package space saving Flat Package, or
a Single In-Line Package.
•Precision voltage detection (VS = 4.2V ±2.5%)
•Threshold level with hysterisis
•Low voltage output for reset signal (VCC = 0.8V typ.)
PLASTIC PACKAGE
FPT-8P-M01
•Precision reference voltage output (VREF = 1.245 V±1.5%)
•External clock monitor and reset signal generator
•Negative-edge input watch-dog timer
•Minimal number of external components (one capacitor min.)
•Available in a variety of packages
• 8-pin Dual In-Line Package
• 8-pin Flat Package
PLASTIC PACKAGE
SIP-8P-M03
• 8-pin Single In-Line Package
This device contains circuitry to protect the inputs
against damage due to high static voltages or
electric fields. However, it is advised that normal
precautions be taken to avoid application of any
voltage higher than maximum rated voltages to this
high impedance circuit.

NOTE: The 5V supply voltage is monitored by the MB3773.
The 12V supply viltage is monitored by the external circuit. Its output is connected to the NMI

• Use VCC1 (=5V) to power the comparators (Comp. 1 and Comp. 2) in the external circuit
shown above.
• The detection voltage of the VCC2 (=12V) supply voltage is approximately 0.2V.
VCC2 detection voltage and hysterisis width can be found using the following formulas:

• Comp. 1 and Comp. 2 are used to monitor for overvoltage while the MB3773 is used to monitor for low

Detection voltages V1/V1H at the time of low voltage areappoximately 4.2V/4.3V. Detection voltages
V2L/V2H at the time of overvoltage are approximately 6.0V/6.1V.
For the formulas for finding hysterisis width and detection voltage, see section 4.

EXAMPLE 8 : Stopping Watch-dog Timer (Monitering only supply voltage)
These are example application circuts in which the MB3773 monitors supply voltage alone without resetting
the microcomputer even if the latter, used in standby mode, stops sending the clock pulse to the MB3773.
•The watch-dog timer is inhibited by clamping the Cr pin voltage to VREF .
The supply voltage is constantly monitored even while the watch-dog timer is inhibited.
For this reason, a reset signal is output at the occurrence of either instataneous disruption or a sudden drop
to low voltage.
Note that in application examples a and b, the hold signal is inactive when the watch-dog timer is inhibited
at the time of resetting.
If the hold signal is active when tie microcomputer is reset, the solution is to add a gate, as in examples c and d.

(b) Standard usage
• RESET is the only output that can be used.
• Standard TPR, TWD and TWR value can be found using the following formulas.
Formulas :
TPR (ms)
100 × CT (µF)
TWD (ms)
100 × CT (µF)
TWR (ms)
16 × CT (µF)
• The above formulas allow fo standard values in determining TPR, TWD and TWR.
Reset hold time is compared below between the reduction circuit and the standard circuit.

Description of Application Circuits
Using one MB3773, this application circuit monitors multiple microcomputers in one system. Signals from each microcomputer
are sent to FF1, FF2 and FF3 clock inputs. Figure 2 shows these timings. Each flip-flop operates using signals sent from microcomputers as its clock pulse. When even one signal stops, the relevant receiving flip-flop stops operating. As a result, cyclical pulses are not generated at output Q3. Since the clock pulse stops arriving at the CK pin of the MB3773, the MB3773
generates a reset signal.
Note that output Q3 frequncy f will be in the following range, where the clock frequencies of CK1, CK2 and CK3 are f1, f2 and f3
respectively.
1 1 1 1 1
---- ≤ --- ≤ ---- + ---- + ---f0 f f1 f2 f3
where f0 is the lowest frequency among f1, f2 and f3.

• This is an example application to limit upper frequency fH of clock pulses sent from the
microcomputer.
If the CK cycle sent from the microcomputer exceeds fH, the circuit generates a reset
signal.
(The lower freqency has already been set using Cr.)
• When a clock pulse such as shown below is sent to pin CK, a short T2 prevents C2 voltage
from reaching the CK input threshold level ( ≅1.25V), and will cause a reset signal to be
output.
The T1 value can be found using the following formula :
T1
≅ 0.3 C2R2
