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 microcomputer reset
voltage detection circuit and low battery detection circuit.
A single reference

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 sy...
