Monolithic IC PST600

System Reset PST600

Outline

This IC operates in a variety of CPU systems and other logic systems by detecting power supply voltage, so

that the system can be reset accurately when power is turned on or when power is momentarily cut. PST572

and others perform the same function as does this series, but this IC is a low reset type system resetting IC

which follows load current so that circuit current flow increases for ON, and has low current consumption for

both ON and OFF.

Features

1. Follows load current so that circuit current flow increases for ON, and has low current consumption for

both ON and OFF.

No load : ICCL=7µA typ.; ICCH=5µA typ.

2. Low operating limit voltage

0.65V typ.

3. Hysteresis voltage provided in detection voltage 50mV typ.

4. The following 10 ranks of detection voltages are available.

PST600 C : 4.5V typ. H : 3.1V typ.

D : 4.2V typ. I : 2.9V typ.

E : 3.9V typ. J : 2.7V typ.

F : 3.6V typ. K : 2.5V typ.

G : 3.3V typ. L : 2.3V typ.

Package

MMP-3A (PST600 M)

TO-92A (PST600 )

* contains detection voltage rank.
