System Reset
Monolithic IC PST611
Outline
This IC functions in a variety of CPU systems and other logic systems, to constantly monitor power supply
voltage, and to reset the system accurately when power is turned on or interrupted.
System reset ICs have been represented by the PST series in the past, but this IC is able to set no-response
time through an external capacitor, and controls reset output relative to temporary power supply voltage drop
caused by motor load or the like in systems using batteries.
Also, the detection voltage for this IC is set low so that it can respond to systems that operate on low voltage.
