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...
