MB3793-37A, POWER-VOLTAGE MONITORING IC WITH WATCHDOG TIMER

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
