The MAX4372 low-cost, precision, high-side currentsense
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 consumes
only 30μA. It features a voltage output that eliminates
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 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 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 voltage
gain and selecting the appropriate external sense
resistor. This capability offers a high level of integration
and flexibility, resulting in a simple and compact current-
sense solution. For higher bandwidth applications,
refer to the MAX4173T/F/H data sheet.
