MM1136 Datasheet (mm1135 / Mm1136) System Reset (with Built-in Watchdog Timer) Monolithic Ic

Manufacturer: Mitsumi Electronics

Overview: ( DataSheet : .. ) 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 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.
