( DataSheet : www.DataSheet4U.com ) MITSUMI System Reset (with built-in watchdog timer) MM1135, MM1136 System Reset (with built-in watchdog timer) Monolithic IC MM1135, MM1136 Outline These 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. Features 1. Accurate voltage drop detection voltage 1. Low battery detection 3.
