The MAX4073 low-cost, high-side current-sense ampli-

fier features a voltage output that eliminates the need

for gain-setting resistors making it ideal for cell phones,

notebook computers, PDAs, and other systems where

current monitoring is crucial. High-side current moni-

toring does not interfere with the ground path of the

battery charger making the MAX4073 particularly useful

in battery-powered systems. The input common-mode

range of +2V to +28V is independent of the supply volt-

age. The MAX4073’s wide 1.8MHz bandwidth makes it

suitable for use inside battery-charger control loops.

The combination of three gain versions and a selec-

table external-sense resistor sets the full-scale current

reading. The MAX4073 offers a high level of integra-

tion, resulting in a simple and compact current-sense

solution.

The MAX4073 operates from a +3V to +28V single sup-

ply and draws only 0.5mA of supply current. This

device is specified over the automotive operating tem-

perature range (-40

space-saving 5-pin SC70 package (half the size of the

SOT23).

For a similar device in a 6-pin SOT23 with a wider com-

mon-mode voltage range (0 to +28V), see the

MAX4173 data sheet.
