MAX4372H - High-Side Current-Sense Amplifier

Download the MAX4372H datasheet PDF. This datasheet also covers the MAX4372F variant, as both devices belong to the same high-side current-sense amplifier family and are provided as variant models within a single manufacturer datasheet.

General Description

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.

Key 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.
