DESCRIPTION
The UTC
88CXX
series is a high-precision voltage detector
developed and foundry using CMOS process. The detection
voltage is fixed internally, with an accuracy of ±2.0%. The CMOS
output is available. Besides,
88CXX
can easily delay a release
signal by attachment of an external capacitor with built-in delay
circuit.

FEATURES
* High-precision detection voltage:
±2.0%
* Hysteresis characteristics: 5% typ
* Ultra-low current consumption satisfied various detection voltage,
1.0μA typ. (V
DD
=2.0V) for
≤1.4V
and 1.2μA typ. (V
DD
=3.5V) for
≥1.5V.
* Available detection voltage from 1.1~6.0V and step by 0.1V.
* Low operating voltage based on detection voltage, 0.8~6.0V for
for
≤1.4V
and 0.95~10V for
≥1.5V.
* Delay time setting by an additional external capacitor.
*Pb-free plating product number: 88CXXL
