FUJITSU SEMICONDUCTOR DATA SHEET DS04-27401-4E ASSP Power Supply Monitor with Watch-Dog Timer MB3773 s DESCRIPTION The Fujitsu MB3773 is designed to monitor the voltage level of a power supply (+5V or an arbitrary voltage) in a microprocessor circuit, memory board in a large-size puter, for example. The MB3773 also contains a watch-dog timer function to detect uncontrol. Table status of processor and reset system/processor. If the circuit’s power supply deviates more than a specified amount, then the MB3773 generates a reset signal to the microprocessor. Thus, the puter data is protected from accidental erasure. When the MB3773 does not receive the clock pulse from the processor...
