MAX4073H

MAX4073T/F/H Low-Cost, SC70, Voltage-Output, High-Side Current-Sense Amplifier General Description The MAX4073 low-cost, high-side current-sense amplifier features a voltage output that eliminates the need for gain-setting resistors making it ideal for cell phones, notebook computers, PDAs, and other systems where current monitoring is crucial. High-side current monitoring does not interfere with the ground path of the battery charger making the MAX4073 particularly useful in battery-powered systems. The input common-mode range of +2V to +28V is independent of the supply voltage. The MAX4073’s wide 1.8MHz bandwidth makes it suitable for use inside battery-charger control loops. The combination of three gain versions and a selectable external-sense resistor sets the full-scale current reading. The MAX4073 offers a high level of integration, resulting in a simple and compact current-sense solution. The MAX4073 operates from a +3V to +28V single supply and draws only 0.5mA of supply cu...
