MM1099BD中文资料三美数据手册PDF规格书

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.

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.
