MAX4375FEUB+T

Product Summary

The MAX4375FEUB+T is a High-Side Current-Sense Amplifier. The MAX4375FEUB+T contains a highside current-sense amplifier, bandgap reference, and comparator with latching output. It features a voltage output that eliminates the need for gain-setting resistors, making them 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 0 to +28V input common-mode range is independent of the supply voltage, which ensures that the current-sense feedback remains viable even when connected to a battery pack in deep discharge. The applications of the MAX4375FEUB+T include Notebook Computers, Portable/Battery-Powered Systems, Smart Battery Packs/Chargers, Cell Phones, Power-Management Systems, General-System/Board-Level Current Monitoring and Precision Current Sources.
