BUILT-IN DELAY CIRCUIT
HIGH-PRECISION VOLTAGE DETECTOR
EC9509C/ 08C
Introduction
(General Description)
The EC9509C / 08C 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
 Power supply monitor for portable equipment
such as electronic organizers, notebook PCs,
cellular phones, digital cameras
 Constant voltage power monitor for cameras,
communication equipment and video
equipment
 Power monitor and reset for CPUs and
microcomputers
Features
 Ultra-low current consumption
1.0 mA typ. (VDD=2.0 V)
