Ultra-Small Package Built-In Delay High-Precision Voltage Detector
CE8809 Series
Ultra-Small Built-In Delay
CE8809 Series
High-Precision Voltage Detector
INTRODUCTION
FEATURES
The CE8809 Series is
a
series of
Ultra-low current consumption:
high-precision voltage detectors with a
built-in delay time generator of fixed time.
developed using CMOS process.
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)
