System Reset (with built-in watchdog timer) MM1035

System Reset (with built-in watchdog timer)

Monolithic IC MM1035

Outline

This IC functions in a variety of CPU systems and other logic systems to generate a reset signal and reset the

system accurately during momentary interruption or lowering of power supply voltage.

It also has a built-in watchdog timer for operation diagnosis. This prevents the system from running wild by

generating an intermittent reset pulse during system mis-operation.
