LR8809 Datasheet Ultra-small Built-in Delay High-precision Voltage Detector

Manufacturer: LRC

Overview: LRCULTRA-SMALL PACKAGE BUILT-IN DELAY HIGH-PRECISION VOLLETASGHE DAETNECRTOARDIO COMPACEN88Y09,LSeTriDes. 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.
