Micropower Voltage Reference with Comparator

ISL21440

Features

• 1.8µA Supply Current Over Full Temperature Range

• Wide Supply Range. . . . . . . . . . . . . . . 2V to 11V

• Precision 1.182V ±0.5% Voltage Reference

• Comparator with User Programmable Hysteresis

• Temperature Range . . . . . . . . . -40°C to +125°C

• 8 Ld MSOP and 8 Ld TDFN Packages

The ISL21440 is a micropower, FGA™ reference and

comparator on a single chip. Drawing less than 1.8µA

supply current over 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.

• Pin Compatible Upgrade to MAX921 and LTC1440

Applications*(see page 13)

• Low Battery Detector

• Low Voltage Reset

The low supply current makes the ISL21440 ideal for

battery powered devices in battery level or low voltage

monitors circuits.

• Overvoltage Monitor

• Window Comparator

The ISL21440 is a pin-compatible, performance upgrade

of both the LTC1440, LTC1540, MAX921 and MAX931.
