System Reset PST90XX
System Reset
Monolithic IC PST90XX Series
Outline
The function of this low voltage detection 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. 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
2. Super low current consumption
3. Low operating threshold voltage
4. Hysteresis voltage is provided as a detect voltage
5. The detect voltage can be selected at your discretion at 0.1 V step within the range of 0.8 to 1.8V by the
following stipulation method.
