System Reset (with built-in watchdog timer)
Monolithic IC MM1142
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. Power supply voltage detection
3. Detection voltage error
4. Hysteresis
2. Watchdog function stop pin (can be made to function only as reset IC during V
