General Description

The MAX9610 high-side current-sense amplifier offers

precision accuracy specifications of V

less than

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.

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).

The three gain versions offer flexibility in the choice of

the external current-sense resistor. The very low 500μV

(max) input offset voltage allows small 25mV to 50mV

full-scale V

SENSE

voltage for very low voltage drop at

full-load current measurement.

The MAX9610 is offered in tiny 6-pin μDFN, (1mm x

1.5mm x 0.8mm footprint) and 5-pin SC70 packages,

specified for operation over the -40°C to +85°C temper-

ature range.

For a very similar 1.6V to 28V input voltage device in a

4-bump UCSP™ package (1mm x 1mm x 0.6mm), refer

to the MAX9938 data sheet.
