UTC 81XX
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, is most suited as a voltage check circuit for a
number of products which use batteries.
FEATURES
*High precision voltage detection. (Vs±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.
UTC 81XX (XX : detected voltage value)
APPLICATIONS
*Reset circuits for microcomputers, CPU and MPU.
*Reset circuit for logic circuitry.
*Battery voltage check circuit.
*Circuit for changing over to backup battery.
*Level detecting circuit.
