♠ Low-Cost, UCSP/SOT23, Micropower, High-Side Current-Sense Amplifier with Voltage Output
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 commonmode 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.
