Low-Cost, SC70, Voltage-Output,
High-Side Current-Sense Amplifier
General Description
Features
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.
o Low-Cost, Compact, Current-Sense Solution
o Three Gain Versions Available
+20V/V (MAX4073T)
+50V/V (MAX4073F)
+100V/V (MAX4073H)
o
1ꢀ0ꢁ Full-Scale Accuracꢂ
o 500µA Supplꢂ Current
o Wide 1ꢀ8MHz Bandwidth
o +3V to +28V Operating Supplꢂ
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.
o Wide +2V to +28V Common-Mode Range
Independent of Supplꢂ Voltage
o Automotive Temperature Range (-40°C to +125°C)
o Available in Space-Saving 5-Pin SC70 Package
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).

critical, use the alternative solution shown in Figure 2.
This solution uses copper PC board traces to create a
sense resistor. The resistivity of a 0.1-inch-wide trace of
2-ounce copper is approxiꢀately 30ꢀΩ/ft. The resis-
tance-teꢀperature coefficient of copper is fairly high
(approxiꢀately 0.4%/°C), so systeꢀs that experience a
wide teꢀperature variance ꢀust coꢀpensate for this
effect. In addition, do not exceed the ꢀaxiꢀuꢀ power
dissipation of the copper trace.

The output of the MAX4073 is a current source driving a
12kΩ resistance. Resistive loading added to OUT
reduces the output gain of the MAX4073. To ꢀiniꢀize
output errors for ꢀost applications, connect OUT to a
high-iꢀpedance input stage. When output buffering is
required, choose an op aꢀp with a coꢀꢀon-ꢀode
input range and an output voltage swing that includes
ground when operating with a single supply. The op
aꢀp’s supply voltage range should be at least as high
as any voltage the systeꢀ ꢀay encounter.
