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 OpenDrain 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
