88CXX
BUILT-IN DELAY CIRCUIT
HIGH-PRECISION VOLTAGE
DETECTOR
DESCRIPTION
The UTC
88CXX
series are highly accurate, low power
consumption voltage detector, manufactured using CMOS process.
The detection voltage is fixed internally, with an accuracy of ±2.0%.
Besides, UTC
88CXX
can easily delay a release signal by
attachment of an external capacitor with built-in delay circuit.
CMOS IC
FEATURES
* Highly accurate
: 2.0%
* Hysteresis characteristics: 5% typ.
* Ultra-low current consumption: 1.0μA typ. (V
DD
=2.0V)
* Detection voltage ranges: 1.5~6V and step by 0.1V.
* Low operating voltage based on detection voltage
* Delay time setting by an additional external capacitor.
