General Description
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
°
C to +125
°
C) and is available in a
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.
