| 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) 270A typ. 4.2V typ. -0.24A typ. 4.4V typ. 0.1V typ. 3.3V typ. 0.3V typ. 0.3V typ. 0.1A typ.

In other words, reset output is output if a clock pulse is not input during this time. 2 Reset time means reset pulse width. However, this does not apply to power ON reset. 3 Reset hold time is the time from when VCC exceeds detection voltage (VSHR) during power ON reset until reset release (RESET output high). 4 Watchdog timer monitoring time (TWD), watchdog timer reset time (TWR) and reset hold time (TPR) during power supply rise can be changed by varying CT capacitance. The times are expressed by the following formulae. Example : when CT=0.02F * * * * ------------------------------------------------ * * * . . TPR = 100mS TPR (mS) = 5000 CT (F) . . . 5000 CT (F) TWD (mS) = TWD . . 100mS = . TWR (mS) . . 100 CT (F) = TWR . . 2mS = 5 The voltage range when measuring output rise and fall time is 10~90%. 6 The IC can be made to operate only as a reset IC with delay during Vcc rise by connecting the RCT pin to GND. 7 VCC rise time should be 100S or more, and fall time should be 50S or more.
