VOLTAGE DETECTOR
EC9518C/
EC9519C
Introduction
(General Description)
The EC9518C / 9519C Series is a high-
precision voltage detector developed using
CMOS process. The detection voltage is fixed
internally with an accuracy of ±2.0 %. A time
delayed reset can be accomplished with the
addition of an external capacitor. Two output
forms, N-channel open-drain and CMOS
output, are available.
Applications
ï¬ Power supply monitor for portable equipment
such as electronic organizers, notebook PCs,
cellular phones, digital cameras
ï¬ Constant voltage power monitor for cameras,
communication equipment and video
equipment
ï¬ Power monitor and reset for CPUs and
microcomputers
