19-1548; Rev 3; 12/05  
Low-Cost, UCSP/SOT23, Micropower, High-Side  
Current-Sense Amplifier with Voltage Output  
General Description  
Features  
The MAX4372 low-cost, precision, high-side current-  
sense amplifier is available in a tiny, space-saving  
SOT23-5-pin package. Offered in three gain versions  
(T = 20V/V, F = 50V/V, and H = 100V/V), this device  
operates from a single 2.7V to 28V supply and con-  
sumes only 30µA. It features a voltage output that elimi-  
nates the need for gain-setting resistors and is ideal for  
today’s notebook computers, cell phones, and other  
systems where battery/DC current monitoring is critical.  
♦ Low-Cost, Compact Current-Sense Solution  
♦ 30µA Supply Current  
♦ 2.7V to 28V Operating Supply  
♦ 0.18% Full-Scale Accuracy  
♦ 0.3mV Input Offset Voltage  
♦ Low 1.5Ω Output Impedance  
High-side current monitoring is especially useful in bat-  
tery-powered systems since it does not interfere with  
the ground path of the battery charger. The input com-  
mon-mode range of 0 to 28V is independent of the sup-  
ply voltage and ensures that the current-sense  
feedback remains viable even when connected to a  
2-cell battery pack in deep discharge.  
♦ Three Gain Versions Available  
20V/V (MAX4372T)  
50V/V (MAX4372F)  
100V/V (MAX4372H)  
♦ Wide 0 to 28V Common-Mode Range,  
Independent of Supply Voltage  
♦ Available in a Space-Saving 5-Pin SOT23 Package  
The user can set the full-scale current reading by  
choosing the device (T, F, or H) with the desired volt-  
age gain and selecting the appropriate external sense  
resistor. This capability offers a high level of integration  
and flexibility, resulting in a simple and compact cur-  
rent-sense solution. For higher bandwidth applications,  
refer to the MAX4173T/F/H data sheet.
