Ge n e ra l De s c rip t io n

Fe a t u re s

The MAX4173 low-cost, precision, high-side current-

sense amplifier is available in a tiny SOT23-6 package.

It features a voltage output that eliminates the need for

gain-setting resistors and it is ideal for today’s notebook

computers, cell phones, and other systems where cur-

rent monitoring is critical. High-side current monitoring

is especially useful in battery-powered systems, since it

does not interfere with the ground path of the battery

charger. The input common-mode range of 0 to +28V is

independent of the supply voltage and ensures that the

current-sense feedback remains viable even when con-

nected to a battery in deep discharge. The MAX4173’s

wide 1.7MHz bandwidth makes it suitable for use inside

battery charger control loops.

♦ Low-Cost, Compact Current-Sense Solution

♦ Wide 0 to +28V Common-Mode Range

Independent of Supply Voltage

♦ Three Gain Versions Available

+20V/V (MAX4173T)

+50V/V (MAX4173F)

+100V/V (MAX4173H)

♦ ±0.5% Full-Scale Accuracy

♦ 420µA Supply Current

♦ Wide 1.7MHz Bandwidth (MAX4173T)

♦ +3V to +28V Operating Supply

♦ Available in Space-Saving SOT23-6 Package

The combination of three gain versions and a user-

selectable external sense resistor sets the full-scale

current reading. This feature offers a high level of inte-

gration, resulting in a simple and compact current-

sense solution.

Typ ic a l Op e ra t in g Circ u it

The MAX4173 operates from a single +3V to +28V sup-

ply, typically draws only 420µA of supply current over

the extended operating temperature range (-40°C to

+85°C), and is offered in the space-saving SOT23-6

package.
