ULTRA-SMALL BUILT-IN DELAY
HIGH-PRECISION VOLTAGE DETECTOR
LR8809 SERIES
„ Introduction
The LR8809 Series is a series of
high-precision voltage detectors with a
built-in delay time generator of fixed
time. developed using CMOS process.
The detection voltage is fixed internally,
with an accuracy of ±2.0 %. Internal
oscillator and counter timer can delay
the release signal without external
parts, delay times 200 mS Two output
forms, Nch pen-drain and CMOS
output are available.
„ Application
• Memory battery back-up circuits
• Power-on reset circuits
• Power failure detection
• Power monitor for portable equipment
such as notebook computers, digital
cameras, PDA, and cellular phones.
• Constant voltage power monitors
for cameras, video equipment and
communication devices.
• Power monitor for microcomputers and
reset for CPUs.
„ Features
• Ultra-low current consumption: 1.0μA@3.5V(typ)
• High-precision detection voltage: ±2.0 %
• Hysteresis characteristics: -VDET ×5%(typ)
• Operating voltage range: 0.95 V to 8.0 V
• Detection voltage: 1.5V to 6.0 V (0.1 V step)
• Delay time: 200 mS(typ)
• Output forms:
NMOS open-drain output (Active Low)
CMOS output (Active Low)
