PST993C

The PST993C is one of the PST993 series.The PST993C is a Monolithic IC.The function of this IC is to accurately reset systems after detecting the supply voltage at the time of switching power on and instantaneous power off in various CPU and other logic systems. Further, this IC can be offered at low cost because it is designed to be simplified allowing for the replacement from reset circuit of discrete configuration.

Features of the PST993C are:(1)Voltage detect precision VS±5% max.;(2)Low consumption current ICCH=300A typ. ICCL=250A typ.;(3)Low operating threshold voltage 0.65V typ.;(4)Hysteresis voltage is provided as detect voltage 50mV typ.;(5)Hysteresis voltage is provided as detect voltage 50mV typ.;(6)Detect voltage, rank PST993, C : 4.5V H: 3.1V D : 4.2V I : 2.9V E : 3.9V J : 2.7V F : 3.6V K: 2.5V G : 3.3V L : 2.3V(Same ranks for PST994 too);(7)Output form PST993 : Constant current load built-in.

The absolute maximum ratings of the PST993C can be summarized as:(1)Storage temperature: TSTG, -40~+125 °C(2)Operating temperature:TOPR,-20~+75 °C;(3)Supply voltage:VCC,-0.3~10 V;(4)Allowable loss:Pd ,300 mW.
