Introduction

AI Translation

The MAX4173 low-cost, precision, high-side current-sense amplifier is available in a tiny SOT23-6 package. It features a voltage output that eliminates the need for gain-setting resistors and it is ideal for today’s notebook computers, cell phones, and other systems where 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 battery in deep discharge. The MAX4173’s wide 1.7MHz bandwidth makes it suitable for use inside battery charger control loops. The combination of three gain versions and a user-selectable external sense resistor sets the full-scale current reading. This feature offers a high level of integration, resulting in a simple and compact current-sense solution. The MAX4173 operates from a single +3V to +28V supply, typically draws only 420μA of supply current over the extended operating temperature range (-40°C to +85°C), and is offered in the space-saving SOT23 package.
