MAX44286

Low-Power, Precision, 4-Bump WLP,

Current-Sense Amplifier

General Description

Features and Beneﬁts

● Ultra-Low Input Offset Voltage and Tiny Gain Error

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.

Allow Sense Resistor to Detect Tiny Currents (nA)

•

30µV (max) Offset Voltage

0.23% (max) Gain Accuracy

● Low Current Consumption Saves Power

12.5μA I for 200kHz Gain Bandwidth

•

● Space-Saving 4-Bump WLP Package

• 0.78mm x 0.78mm x 0.35mm

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.

● Industry-Leading Low-Power Supply Range

•

1.6V to 5.5V Input Common Mode

● Four Gain Options Offer Flexibility in Sense Resistor

Selection

•

G = 25V/V (MAX44286T)

G = 50V/V (MAX44286F)

G = 100V/V (MAX44286H)

G = 200V/V (MAX44286W)

The MAX44286 operates with a supply voltage range

of 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.
