MITSUMI System ResetPST600/PST600DSystem ResetMonolithic IC PST600OutlineThis IC operates in a variety of CPU systems and other logicsystems by detecting power supply voltage, sothat the system can be reset accurately when power is turned on orwhen power is momentarily cut. PST572and others perform the same function as does this series, but thisIC is a low reset type system resetting ICwhich follows load current so that circuit current flow increasesfor ON, and has low current consumption forboth ON and OFF.Features1. Follows load current so that circuit current flow increases forON, and has low current consumption forboth 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.
