MB3771 Power Supply Monitor

MB3771 Power Supply Monitor

The Cypress 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.

Features
