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.
