AP8821 Series
Anwell Semiconductor Corp.
Ultra-Low Quiescent Current Voltage Detector
Features
General Description
l Ultra-Low Quiescent Current 1.0 µA (Typ.)
l High Accuracy of Detection Voltage ±2%
l Hysteresis Width 5% VDET (Typ.)
l Detection Voltage 1.6V to 6.0V (0.1V Step)
The AP8821 series are highly accurate, ultra-low
current consumption voltage detectors, developed
by CMOS process. Two output forms N-channel
open-drain and CMOS output are available. The
device is ideal for battery powered portable devices
which require low current consumption.
l Operating Voltage Range 1.5V to 6.0V
l N-ch Open Drain and CMOS Output
l SOT-23, SC-82 and SC-70 Packages
l RoHS Compliant and 100% Lead (Pb)-Free
The AP8821 consists of a comparator, a voltage
reference unit, a resistor divider, an output driver,
and a hysteresis circuit. The detection voltage is
fixed internally with ±2.0% accuracy by advanced
trimming technology.
and Green (Halogen Free with Commercial
Standard)
The devices are available in SOT-23,SC-82 and
SC-70 packages.
