Ultra-Small Built-In Delay High-Precision Voltage Detector

CJ809 Series

 INTRODUCTION

 FEATURES

The CJ809 Series is a series of high-

recision voltage detectors with a built-

in delay time generator of fixed time.

developed using CMOS process.



Ultra-low current consumption:

0.9μA@3.5V(Typ.)



High-precision detection voltage: ±2.0%

Hysteresis characteristics: -VDET×5%(Typ.)

Operating voltage range: 0.95V to 7.0V

Detection voltage: 1.5V to 6.0V (10mV step)

Delay time: 210 ms (Typ.)

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, NMOS

open-drain and CMOS output are available.

Output forms:

NMOS open-drain output (Active Low)

CMOS output (Active Low)
