PST600C中文资料三美数据手册PDF规格书

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.

Applications

1. Microcomputers, CPU, MPU reset circuits

2. Logic circuit reset circuits

3. Battery voltage check circuits

4. Back-up power supply switching circuits

5. Level detection circuits
