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.
Features
1. Built-in watch dog timer
2. Low current consumption
3. Low operating threshold voltage
4. Watch dog stop function (RCT terminal)
5. Long clock monitoring time
