MAX4372FEUK+T

The MAX4372FEUK+T is a low cost, micropower, high side current sense amplifier with voltage output in 5 pin SOT23 package. 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. It is typically used at 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.
