Low-Cost / SOT23 / Voltage-Output / High-Side Current-Sense Amplifier
General DescriptionThe 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.
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.
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.
