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

*low current consumption.

*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.
