System Reset PST993, 994
System Reset
Monolithic IC PST993, 994
Outline
The function of this IC is to accurately reset systems after detecting the supply voltage at the time of
switching power on and instantaneous power off in various CPU and other logic systems. Further, this IC can
be offered at low cost because it is designed to be simplified allowing for the replacement from reset circuit of
discrete configuration.
Features
1. Voltage detect precision
2. Low consumption current
3. Low operating threshold voltage
4. Hysteresis voltage is provided as detect voltage
5. Large output current at the time ON
6. Detect voltage rank
