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.

FEATUREs
1. Low current consumption ICCH=2.2µA ICCL=3.2µA
2. Low operating limit voltage 0.75V max.
3. High reset output
4. No-response time can be controlled
5. 8 types of detection voltages provided PST611 R : 1.6V typ. V : 1.2V typ.
                                                                                S : 1.5V typ. W: 1.1V typ.
                                                                                T : 1.4V typ. X : 1.0V typ.
                                                                                U : 1.3V typ. Y : 0.9V typ.

APPLICATIONs
1. Reset circuits in microcomputers, CPUs and MPUs
2. Set voltage drop detection
3. Battery voltage check circuits.
4. Voltage detection circuits in general
