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 130µA TYP.
3. Low operating threshold voltage VCC=0.8V
4. Watch dog stop function (RCT terminal)
5. Long clock monitoring time TPR (POWER ON) : TWD (clock monitoring)=1 : 1
6. Fewer outer components

APPLICATIONs
1. Reset circuit for microcomputers, CPU and MPU.
2. Reset circuit for logic circuitry.
3. Monitoring of microcomputer system, etc.
