A4806
HIGH-PRECISION, ULTRA LOW CURRENT CONSUMPTION
LOW VOLTAGE DETECTOR
DESCRIPTION
FEATURES
The A4806 is a series of high precision voltage
detector with ultra low current consumption
(500nA typ. at VDD=3.0V).
The A4806 can work at very low voltage, which
makes it perfect for system reset.
The A4806 is composed of high precision voltage
reference, comparator, and output driver and
resistor array. Internally preset detect voltage
has a low temperature drift and requires no
external trimming.
Two type of output; CMOS and N-Channel Open-
Drain are available.
A4806 is available in SOT-23 & SOT-25 package.
High-Precision Detection Voltage: ±2%
Detection Voltage: 0.9V~6.0V(in 0.1V step)
Precise Hysteresis: 4% typ.
Operating Voltage Range: 0.7V~10V
Untra-Low Current Consumption: 0.5uA typ. (at
VDD=3.0V)
Two Output Forms: CMOS and N-Channel
Open-Drain
Available in SOT-23 and SOT-25 package
APPLICATION
Power Monitor for Portable Equipment such as
PDA, DSC, Mobile Phone, Notebook, MP3
CPU and Logic Circuit Reset
Battery Checker
Battery Back-Up Circuit
Power Failure Detector
