Product Summary
The mb3771pf-g-bnd-er- is a Power Supply Monitor. The mb3771pf-g-bnd-er- 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. Thus, the computer data is protected from accidental erasure. Using the mb3771pf-g-bnd-er- requires few external components. To monitor only a +5 V supply, the mb3771pf-g-bnd-er- requires the connection of one external capacitor. The level of an arbitrary detection voltage is determined by two external resistors. The mb3771pf-g-bnd-er- is available in an 8-pin Dual In-Line, Single In-Line Package or space saving Flat Package.
