Product Summary

The MAX4376FASA is a single precision high-side current-sense amplifier. It is available in space-saving packages. It features buffered voltage outputs that eliminate the need for gain-setting resistors and is ideal for today’s notebook computers, cell phones, and other systems where current monitoring is critical. The MAX4376FASA operates over a supply voltage range of +3V to +28V, draw 1mA of supply current per amplifier, and operate over the full automotive temperature range of -40℃ to +125℃. The applications of the MAX4376FASA include: Notebook Computers, Current-Limited Power Supplies, Fuel Gauges in PC, General-System/Board-Level Current Monitoring, Battery Chargers, Portable/Battery-Powered Systems, Cell Phones, Smart Battery Packages, Automotive Current Detect, Power Management Systems, PA Bias Control.
