ISL21440
Micropower Voltage Reference with Comparator
The ISL21440 is a micropower, FGA reference, and comparator on a single chip. Drawing less than 6.5µA supply current across the full operating temperature range, the ISL21440 operates from a single 2V to 11V supply and can also be used with split bipolar supplies.
The ISL21440’s on-board reference provides a 1.182V ±0.5% output. It features programmable hysteresis and TTL/CMOS compatible outputs that sink and source current. Low bias currents permit high value divider resistors for typical circuit current drains of <2.5µA.
The low supply current makes the ISL21440 ideal for battery powered devices in battery level or low voltage monitor circuits.
