Power Supply Monitor
MB3771
■ DESCRIPTION
The Fujitsu MB3771 is designed to monitor the voltage level of one or two power supplies (+5 V and an arbitrary
voltage) in a microprocessor circuit, memory board in large-size computer, for example.
If the circuit’s power supply deviates more than a specified amount, then the MB3771 generates a reset signal to
the microprocessor. Thus, the computer data is protected from accidental erasure.
Using the MB3771 requires few external components. To monitor only a +5 V supply, the MB3771 requires the
connection of one external capacitor. The level of an arbitrary detection voltage is determined by two external
resistors. The MB3771 is available in an 8-pin Dual In-Line, Single In-Line Package or space saving Flat Package.
■ FEATURES
• Precision voltage detection (VSA = 4.2 V ± 2.5 %)
• User selectable threshold level with hysterisis (VSB = 1.23 V ± 1.5 %)
• Monitors the voltage of one or two power supplies (5 V and an arbitrary voltage, >1.23 V)
• Usable as over voltage detector
• Low voltage output for reset signal (VCC = 0.8 V typ.)
• Minimal number of external components (one capacitor min.)
• Low power dissipation (ICC = 0.35 mA typ., VCC = 5 V)
• Detection threshold voltage has hysteresis function
• Reference voltage is connectable.

■ FUNCTIONAL DESCRIPTIONS
Comparators Comp.A and Comp.B apply a hysteresis to the detected voltage, so that when the voltage at either
the VSA or VSB pin falls below 1.23 V the RESET output signal goes to “low” level.
Comp. B may be used to detect any given voltage(Sample Application 3), and can also be used as a forced
reset pin (with reset hold time) with TTL input (Sample Application 6).
Note that if Comp.B is not used, the VSB pin should be connected to the VCC pin (Sample Application 1).
Instantaneous breaks or drops in the power supply can be detected as abnormal conditions by the MB3771
within a 2 µs interval. However because momentary breaks or drops of this duration do not cause problems in
actual systems in some cases, a delayed trigger function can be created by connecting capacitors to the VSA or
VSB pin (Sample Application 8).
Because the RESET output has built-in pull-up resistance, there is no need to connect to external pull-up
resistance when connected to a high impedance load such as a CMOS logic IC.
Comparator Comp. C is an open-collector output comparator without hysteresis, in which the polarity of input/
output characteristics is reversed. Thus Comp. C is useful for over-voltage detection (Sample Application 11)
and positive logic RESET signal output (Sample Application 7), as well as for creating a reference voltage
(Sample Application 10).
Note that if Comp. C is not used, the VSC pin should be connected to the GND pin (Sample Application 1).

(1) When VCC rises to about 0.8V, RESET goes low.
(2) When VCC reaches VS +VHYS, CT then begins charging. RESET remains low during this time
(3) RESET goes high when CT begins charging.
TPO =: CT × 10 5 (Refer to CT pin capacitance vs. hold time )
(4) When VCC level dropps lower then VS, then RESET goes low and CT starts discharging.
(5) When VCC level reaches VS + VHYS, then CT starts charging.
In the case of voltage sagging, if the period from the time VCC goes lower than or equal to VS to the time VCC
reaches VS +VHYS again, is longer than tPI, (as specified in the AC Characteristics), CT is discharged and charged
successively.
(6) After TPO passes, and VCC level exceeds VS + VHYS, then RESET goes high.
(7) Same as Point 4.
(8) RESET remains low until VCC drops below 0.8V.

2. 5V Power Supply Voltage Monitor (Externally Fine-Tuned Type)
The VSA detection voltage can be adjusted externally.
Resistance R1 and R2 are set sufficiently lower than the IC internal partial voltage resistance, so that the detection
voltage can be set using the ratio between resistance R1 and R2. (See the table below).
• R1, R2 calculation formula (when R1 << 100 kΩ, R2 <<40 kΩ)

3. Arbitrary Voltage Supply Monitor
(1) Case: VCC ≤ 18 V
• Detection Voltage can be set by R1 and R2.
Detection Voltage = (R1 + R2) × VSB/R2
• Connect Pin 7 to VCC when VCC less than 4.45 V.
• Pin 7 can be opened when VCC greater than 4.45 V
Power Dissipation can be reduced.
Note : Hysteresis of 28 mV at VSB at termination is available.
Hysteresis width dose not depend on (R1 + R2).

(2) Monitoring VCC > 18 V
• Detection Voltage can be set by R1 and R2
Detection Voltage = (R1 + R2) × VSB/R2
• The RESET signal output is =: 0V (low level) and =: 5 V (high level). VCC voltage cannot be output.
Do not pull up RESET to VCC.
• Changing the resistance ratio between R4 and R5 changes the constant voltage output, thereby changing the
voltage of the high level RESET output. Note that the constant voltage output should not exceed 18 V.
• The 5 V output can be used as a power supply for control circuits with low current consumption.
• In setting the R3 resistance level, caution should be given to the power consumption in the resistor. The table
below lists sample resistance values for reference (using 1/4 Ω resistance).

• Values are actual measured values (using IOUTC = 100 µA, VOLC = 0.4 V). Lowering the resistance value of R3
reduces the minimum supply voltage of the RESET output, but requires resistance with higher allowable loss.

9. Dual (Positive/Negative) Power Supply Voltage Monitoring (VCC = 5 V, VEE = Negative Power
Supply)
Monitors a 5 V and a negative (any given level) power supply. R1, R2, and R3 should be the same value.
Detection Voltage = VSB - VSB × R4/R3
Example if VEE = -5 V, R4 = 91 kΩ
Then the detected voltage = -4.37 V
In cases where VEE may be output when VCC is not output, it is necessary to use a Schottky barrier diode (SBD).

• Use CMOS Logic and connect VDD of CMOS logic with VCCO.
• The back-up battery works after CS goes high as V2 < V1.

When V1 is 4.45 V or less, connect 7 pin with VCC.
When V1 is 4.45 V or more, 7 pin can be used to open.
• The voltage to change V2 is provided as the following equation:
V2 = VF + (R1 + R2 + R3) × VSC/ (R2 + R3)

Any semiconductor devices have inherently a certain rate of
failure. You must protect against injury, damage or loss from
such failures by incorporating safety design measures into your
facility and equipment such as redundancy, fire protection, and
prevention of over-current levels and other abnormal operating
conditions.
