System Reset PST91XX
System Reset
Monolithic IC PST91XX Series
Outline
The function of this low reset type 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, with its super low consumption current and high precision voltage detection capacity, is most suited as a
voltage check circuit for a number of products which use batteries.
Features
1. High precision voltage detection
Vs±3% max.
2. Super low current consumption
ICCH=1.5µA typ. ICCL=1.0µA typ.
3. Low operating threshold voltage
0.65V typ.
4. Hysteresis voltage is provided as a detect voltage 50mV typ.
5. Large output current at the time ON
15mA typ.
6. The detect voltage can be selected at your discretion at 0.1V step within the range of 1.9 to 4.6V by the
following stipulation method.
