Fujitsu MB3773
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 computer, for example. The MB3773 also contains a watch-dog timer function to detect uncontrol. If the circuit’s power supply deviates more than a specified amount, then the MB3773 generates a reset signal to the microprocessor.| Part No. | MB3773 |

DESCRIPTION
The Fujitsu Table status of processor and reset system/processor. Thus, the computer data is protected from accidental erasure. When the MB3773 does not receive the clock pulse from the processor in the specified period, the MB3773 generates a reset signal to the mciroprocessor. Using the MB3773 requires few external components. To monitor only a +5 volt supply, the MB3773 requires the connection of one external capacitor. The MB3773 is available in an 8-pin Dual In-Line package space saving Flat Package, or a Single In-Line Package.●Precision voltage detection (VS = 4.2V ±2.5%)
●Threshold level with hysterisis
