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 N-channel open drain output.
The detector threshold is set from 2.0V to 6.0V in 0.1V 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.
