EC9508C/09C-BUILT-IN DELAY Voltage Detector

EC9508C/EC9509C-BUILT-IN DELAY Voltage Detector
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.

Features
◆Ultra-low current consumption

1.0 mA typ. (VDD=2.0 V)

1.1 mA typ. (VDD=3.5 V)

◆High-precision detection voltage ±2.0 %

◆COperating voltage range 2.0 V to 6.0 V

◆Detection voltage 2.2 V to 3.1 V (0.1 V step)

◆Hysteresis characteristics 5 % typ.

◆Two output forms: CMOS output active “L” Open-drain output active “L”

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
