MB3793-30A Power Voltage Monitoring IC with Watchdog Timer Datasheet Description The MB3793 is an integrated circuit to monitor power voltage it incorporates a watchdog timer. A reset signal is output when the power is cut or falls abruptly. When the power recovers normally after resetting, a power-on reset signal is output to microprocessor units (MPUs). An internal watchdog timer with two inputs for system operation diagnosis can provide a fall-safe function for various application systems. Features Precise detection of power voltage fall: 2.5% Detection voltage with hysteresis Low power dispersion: I = 31 A (reference) CC Internal dual-input watchdog timer Watchdog-timer halt function (by inhibition pin) Independently-set watchdog and reset times Three types of packages (SOP-8pin) : 2 types Application Arcade Amusement etc. Cypress Semiconductor Corporation 198 Champion Court San Jose, CA 95134-1709 408-943-2600 Document Number: 002-08554 Rev. *C Revised June 29, 2017MB3793-30A Contents Description ................................................... 1 8.
