Low-Cost, UCSP/SOT23, Micropower, High-Side

Current-Sense Amplifier with Voltage Output

General Description

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.

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.

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.
