Overview
19-4342; Rev 0; 10/08 MAX9610 1µA, µDFN/SC70, Lithium-Ion Battery, Precision Current-Sense Amplifier General Description The MAX9610 high-side current-sense amplifier offers precision accuracy specifications of VOS less than 500μV (max) and gain error less than 0.
5% (max).
This device features an ultra-low 1μA quiescent supply current.
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 (Li+) battery-operated portable devices where accuracy, low quiescent current, and small size are critical.
The MAX9610 features an input voltage range (common mode) from 1.
6V to 5.
5V.
This input range is excellent for monitoring the current of a single-cell, lithium-ion battery, 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 versions: 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 VSENSE 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 temperature range.

6V to 28V input voltage device in a 4-bump UCSP™ package (1mm x 1mm x 0.
6mm), refer to the MAX9938 data sheet.
