UNISONIC TECHNOLOGIES CO., LTD 82XX Preliminary LINEAR INTEGRATED CIRCUIT MONOLITHIC IC 82XX SERIES DESCRIPTION The normal operation of the UTC 82XX is that while the power is turned on or interrupted, detect power supply voltage and then reset the system accurately. The internal circuits of the UTC 82XX include a built-in fixed delay time generating circuit. With a counter timer using an analog/digital hybrid circuit, the UTC 82XX as new low reset type system reset ICs expands the delay time series. These ICs can be used in a variety of CPU systems and other logic systems. FEATURES * Internal Fixed Delay Time Setting by Counter Timer * Grate Delay Time Temperature Characteristics:±800ppm/°C * Operating Limit Voltage as 0.65V(Typ.) * Hysteresis Voltage Provided: 50mV(Typ.) * Circuit Current While On ICCL=300µA(Typ.) * Circuit Current While Off ICCH=200µA(Typ.)
