MITSUMI 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 VS±5% max. ICCH=300µA typ. ICCL=250µA typ. 0.65V typ. 50mV typ. 15mA typ. PST993 C : 4.5V H : 3.1V D : 4.2V I : 2.9V E : 3.9V J : 2.7V F : 3.6V K : 2.
