General Description

The MAX4173 evaluation kit (EV kit) is a fully assembled

and tested surface-mount PCB that contains a

MAX4173TEUT+. The MAX4173 is a high-side, current-

sense amplifier with an input common-mode voltage

range that extends from 0 to 28V. The current-sense

amplifier provides an analog voltage output proportion-

al to the load current flowing through an external sense

resistor.

The 20V/V gain version of the MAX4173 (MAX4173TEUT+)

and a 150mΩ sense resistor are installed on the board.

Other gain versions of the MAX4173 can be evaluated

by replacing the MAX4173TEUT+ with a MAX4173FEUT+

(50V/V) or a MAX4173HEUT+ (100V/V) and a user-sup-

plied, external sense resistor. The user can easily

match the full-scale sense voltage to the required out-

put-voltage range.

Features

o Real-Time Current Monitoring

o Wide 0 to 28V Input Common-Mode Range

Independent of Operating Supply Voltage

o ±0.5% Full-Scale Accuracy

o Lead(Pb)-Free and RoHS Compliant

o Fully Assembled and Tested

Evaluates: MAX4173 MAX4173 Evaluation Kit Quick Start Detailed Description of Hardware Recommended Equipment The MAX4173 IC is a current-sense amplifier that measures the load current and provides an analog voltage output. The full-scale VSENSE is set to 150mV. The fullscale ISENSE is set at 1A. They can be changed by replacing current-sense resistor R1 to another appropriate value.
