The Fujitsu Semiconductor MB3773P is an integrated circuit designed for power supply voltage monitoring and system protection. It generates a reset signal when the power supply voltage momentarily drops or decreases below a specified threshold, safeguarding computer data from accidental deletion.
Key features include precision voltage detection with a typical VS of 4.2V ± 2.5% and a precision reference voltage output (VR) of 1.245V ± 1.5%. The device incorporates a hysteresis function for detection thresholds and a built-in watchdog timer that generates a reset signal if the processor fails to provide clock pulses within a specified period, enabling fail-safe functions in microprocessor systems.
The MB3773P offers a low voltage reset signal output (typically 0.8V at VCC = 0.8V) and supports both positive and negative reset signal outputs. It requires few external components, with one capacitor typically needed for timing functions. The IC is available in a compact SOP-8 pin package, suitable for surface mount applications.
Applications for the MB3773P include industrial equipment and arcade amusement devices where reliable power monitoring and system reset capabilities are crucial for operational integrity.
