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 todays 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 MAX4173s  
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.
