描述 Description

Monolithic IC MM1135, MM1136These ICs were developed to drive low voltage batteries, and have a watchdog timer with built-in microcomputer reset voltage detection circuit and low battery detection circuit.

A single reference voltage is used for low battery voltage detection and microcomputer 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.
