Product Summary

The MAX4372TEUK is a low-cost, precision, high-side current-sense amplifier. It 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 MAX4372TEUK 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. The applications of the MAX4372TEUK include Power-Management Systems, General-System/Board-Level Current Monitoring, Notebook Computers, Portable/Battery-Powered Systems, Smart-Battery Packs/Chargers, Cell Phones and Precision-Current Sources.
