The Fujitsu MB3771 is designed to monitor one or two supply voltages (+5 V and an arbitrary voltage) in microprocessor circuits, for example, in large form factor computer memory boards. If the power supply deviating from the circuit exceeds the specified amount, then the MB3771 generates a reset signal to the microprocessor. Therefore, the computer's data is protected from accidental...
