MCU监控芯片/MB3771PF
■DESCRIPTION
The MB3771 is designed to monitor the voltage level of one or two power supplies +5 V and an arbitrary voltage in a microprocessor circuit, memoryboard 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 datais 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.
