MM1106

MITSUMI System Reset (with watchdog timer+battery back-up) MM1106 System Reset (with watchdog timer+battery back-up) Monolithic IC MM1106 Outline This IC combines the popular watchdog timer with a battery back-up, resulting in an IC that is easier to use. The watchdog timer has a built-in power ON reset function, and both the timer and the battery back-up section have low current consumption. Features 1. Low current consumption 2. Watchdog timer Detection voltage CT charging current 3. CS CS detection voltage Output voltage low level 4. Battery back-up Power supply switching voltage Input/output voltage difference (normal) Input/output voltage difference (back-up) Loss current (current consumption for back-up) 270µA typ. 4.2V typ. -0.24µA typ. 4.4V typ. 0.1V typ. 3.3V typ. 0.3V typ. 0.3V typ. 0.1µA typ. Package SOP-14B (MM1106XF) DIP-14A (MM1106XD) Applications 1. 2. 3. 4. 5. Fax machines Photocopiers Air conditioners Control equipment Sequencers, etc. (Ta=25°C) Symbol VCC max.
