EVALUATION KIT AVAILABLE

MAX44286

Low-Power, Precision, 4-Bump WLP,

Current-Sense Amplifier

General Description

The MAX44286 is a zero-drift, high-side current-sense

amplifier family that offers precision, low supply cur-

rent and is available in a tiny 4-bump ultra-thin WLP of

0.78mm x 0.78mm x 0.35mm footprint. This miniature size

is of paramount for today’s applications in smartphones,

mobile accessories, notebooks, portable medical, and all

battery-operated portable devices where current monitor-

ing with precision and space are critical.

The MAX44286 has voltage output offered in four gain

versions of 25V/V, 50V/V, 100V/V, and 200V/V. These

four gain versions offer flexibility in the choice of the

sense resistor and the very low input offset voltage helps

in detecting small currents on the orders of low micro-

amps. Low power capability also offers the possibility of

minimizing power dissipation.

The MAX44286 operates with a supply voltage range

1.6V to 5.5V over the -40

°C

to +85

°C

temperature

range and

from 1.8V to 5.5V over the -40°C to +125°C

automotive temperature range. Supply voltage for the

device is shared with the RS+ pin to fit the MAX44286 in

a 4-bump, ultra-thin WLP package.
