LINEAR INTEGRATED CIRCUIT
POWER RESET IC
DESCRIPTION
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, UTC 81XX is the most suited as a
voltage check circuit for a number of products which use batteries.
FEATURES
*High Precision Voltage Detection. (VSS±3% Max)
*Low Current Consumption.
(ICCH=15µA typ. ICCL=10µA Typ.)
*Low Operating Threshold Voltage (0.65V Typ.)
*Hysteresis 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.
