MM1142规格书详情
Outline
This IC was developed to drive low voltage batteries, and has 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 2.2V±3
2. Power supply voltage detection 2.0V±3
3. Detection voltage error 0.2V±20mV 1-2
4. Hysteresis both 50mV typ.
2. Watchdog function stop pin (can be made to function only as reset IC during VCC rise)
3. Low current consumption 150µA typ.
Applications
1. 2V cordless telephones
2. Portable communication equipment
3. Various types of small, handy equipment
