A4805
SUPERVISOR (RESET IC)
HIGH VOLTAGE HIGH PRECISION VOLTAGE DETECTOR
DESCRIPTION
FEATURES
The A4805 is a series of high voltage
high-precision voltage detectors developed
using standard CMOS process. The detection
voltage is fixed internally with an accuracy of
±2.4% Nch open-drain.
Low current consumption and miniature package
lineup can meet demand from the portable
device applications.
A4805 is available in SOT-89-3 & TO-92
packages.
Low current consumption 3μA typ.(VIN=8V)
High-precision detection voltage ±2.4%
Operating voltage range -0.3 V to 22 V
Detection voltage 2.4 V to 7.0 V (0.1V step)
Output form Nch open-drain output (Active Low)
Available in SOT-89-3 & TO-92 packages
APPLICATION
Battery checkers
Power failure detectors
Power monitor for portable equipments such as
pagers, calculators, electronic notebooks and
remote controllers.
Constant voltage power monitor for cameras,
video equipments and communication devices.
Power monitor for microcomputers and reset for
CPUs.
