UNISONIC TECHNOLOGIES CO., LTD 81XX LINEAR INTEGRATED CIRCUIT POWER RESET IC 3 DESCRIPTION 1 2 The function of UTC 81XX is to accurately reset system 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, with its super low consumption current and high precision voltage detection capacity, is most suited as a voltage check circuit for a number of products which use batteries. 1 TO-92 SOT-23 3 2 1 1 5 4 FEATURES SOT-25 *High precision voltage detection. (VSS±3% max) *low current consumption. (ICCH=15µA typ. ICCL=10µA typ.) *Low operating threshold voltage (0.65V typ.) *Hystresis voltage is provided as a detect voltage. (50mV typ.) *Large output current at the time ON (15mA typ.) *The detect voltage can be selected at your discretion at 0.1V step within the range of 1.9V to 4.6V by the following stipulation method.
