UNISONIC TECHNOLOGIES CO., LTD
81CXX/81NXX
CMOS IC
VOLTAGE DETECTORS WITH
BUILT-IN DELAY TIME

DESCRIPTION
The UTC 81CXX and 81NXX series are good performance
voltage detector and manufactured by CMOS technologies with
highly accurate, low power consumption. A delay circuit is built-in
to each detector, therefore, peripherals are unnecessary and high
density mounting is possible. Detect voltage is extremely accurate
with minimal temperature drift. Both CMOS and N-channel open
drain output configurations are available.

FEATURES
* Highly Accurate:
* Built-In Delay time :
Detect voltage ± 2%
1ms ~ 50ms
50ms ~ 200ms
200ms ~ 400ms
* Detect Voltage Temperature
Characteristics:
TYP± 100ppm/°C
* Wide Operating Voltage Range : 0.7V ~ 10.0V
* Low Current Consumption :
TYP 1.0μA (VIN=2.0V)

Note: The power consumption during power-start to output being stable (release operation) is 2μA greater than it is
after that period (completion of release operation) because of delay circuit through current.
