ULTRA-SMALL BUILT-IN DELAY

HIGH-PRECISION VOLTAGE DETECTOR

LR8809 SERIES

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.

Features

• Ultra-low current consumption: 1.0μA@3.5V(typ)

• High-precision detection voltage: ±2.0 %

• 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)

• 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.
