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 (V^SB= 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 (V^CC= 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.
