System Reset (Built-in Watch Dog Timer) MM1099
System Reset (Built-in Watch Dog Timer)
Monolithic IC MM1099
Outline
The function of this IC series MM1099 is to accurately reset systems, a generating reset signal at the time of instantaneous supply voltage off or lowering in varied CPU and other logic system. Further, with the watch dog timer built-in it can diagnose the operation of the system, intermittently generating reset pulses when they operate erroneously to prevent runaway.
