Precision Current-Sense Amplifier

MAX9610

General Description

Features

♦ Ultra-Low Supply Current of 1µA (max)

The MAX9610 high-side current-sense amplifier offers

precision accuracy specifications of V less than

♦ Low 500µV (max) Input Offset Voltage

♦ Low < 0.5% (max) Gain Error

♦ Input Common Mode: +1.6V to +5.5V

♦ Voltage Output

500μV (max) and gain error less than 0.5% (max). This

device features an ultra-low 1μA quiescent supply cur-

rent. The MAX9610 fits in a tiny, 1mm x 1.5mm μDFN

package or a 5-pin SC70 package, making this part

ideal for applications in notebook computers, cell

phones, cameras, PDAs, and all lithium-ion battery-

operated portable devices where accuracy, low quies-

cent current, and small size are critical.

♦ Three Gain Versions Available

25V/V (MAX9610T)

50V/V (MAX9610F)

The MAX9610 features an input voltage range (com-

mon mode) from 1.6V to 5.5V. This input range is excel-

lent for monitoring the current of a single-cell,

lithium-ion battery (Li+), which at full charge is 4.2V,

typically 3.6V in normal use, and less than 2.9V when

ready to be recharged. These current-sense amplifiers

have a voltage output and are offered in three gain ver-

sions: 25V/V (MAX9610T), 50V/V (MAX9610F), and

100V/V (MAX9610H).
