UNISONIC TECHNOLOGIES CO., LTD
81CXXX/81NXXX
VOLTAGE DETECTORS WITH
BUILT-IN DELAY TIME
DESCRIPTION
The UTC
81CXXX
and
81NXXX
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.
