Overview: .. MITSUMI System Reset (with built-in watchdog timer) MM1142 System Reset (with built-in watchdog timer) Monolithic IC MM1142 Outline This IC was developed to drive low voltage batteries, and has a watchdog timer with built-in microputer reset voltage detection circuit and low battery detection circuit. A single reference voltage is used for low battery voltage detection and microputer reset voltage . detection, so detection voltage difference is uniform ( = . 0.2V). Further, there is a built-in watchdog timer for operation diagnosis, which prevents the system from running wild by generating an intermittent reset pulse during system mis-operation.
