com 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.
