GENERAL DESCRIPTION

The AMS26 series are voltage detector ICs featuring a high accuracy detector threshold of ±2.0% and ultra-low supply current.

Internal circuit contains a precision voltage reference, a comparator, resistor network, and an output driver. The AMS26 has an

NPN open collector output. The detector threshold is set from 1.45V to 4.6V in 0.05V increments and 4.6V to 7.9 in 0.1V

increments. Also available from 7.9V to 12V in 170mV increments, thus making it easy to use in a variety of supervisory

applications including microprocessor reset circuits, memory battery back-up circuit, battery checker, power failure detector

and portable and battery powered electronics.

AMS26 is available in TO-92 and the sub-miniature 3-pin SOT-23 surface mount package.
