MB3771 Datasheet (Fujitsu) - Power Supply Monitor

MB3771, Power Supply Monitor

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 res

MB3771 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)
