1 / 6 page  Evaluates: MAX44285 MAX44285 Evaluation Kit General Description The MAX44285 evaluation kit (EV kit) provides a proven design to evaluate the MAX44285 dual-channel, high- precision, high-voltage, current-sense amplifier. This EV kit demonstrates the MAX44285 in an ultra-small, 1mm x 2mm, 8-bump WLP package. The EV kit PCB comes with a MAX44285TAWA+ installed, which is the 20V/V gain version. Other gain options are available. Contact the factory for the pin-compatible MAX44285LAWA+ (G = 12.5V/V), MAX44285FAWA+ (G = 50V/V), and MAX44285HAWA+ (G = 100V/V). EV Kit Contents ● MAX44285 EV Kit Board Features and Benefits ● Precision Real-Time Current Monitoring ● +2.7V to +76V Input Common-Mode Range ● Proven PCB Layout ● Fully Assembled and Tested Quick Start Required Equipment The following items are required for operation: • MAX44285 EV kit • +3.3V, 1A DC power supply • +5V, 3A DC power supply • An electronic load capable of sinking 3A (i.e., HP6060B) • Two digital voltmeters Procedure The MAX44285 EV kit is fully assembled and tested. Follow the steps below to verify the board operation. Caution: Do not turn on power supply or the electronic load until all connections are made. 1) Connect the positive terminal of the +3.3V supply to the VDD test point and the negative terminal of the supply to the nearest GND test point. 2) Connect the positive terminal of the +5V supply to the VSENSE+ test point and the negative terminal of the supply to the nearest GND test point. 3) Set the electronic load to sink 2.5A. 4) Connect the positive terminal of the electronic load to the VSENSE- test point and the negative terminal of the supply to the nearest GND test point. 5) Connect the first voltmeter between test points RS1+ and RS1- to measure VSENSE1. 6) Connect the second voltmeter between VOUT1 and the nearest GND test points. 7) Turn on the power supplies. 8) Enable the electronic load. 9) Verify that the first voltmeter displays 125mV and the second voltmeter displays 2.5V. 10) Repeat the steps for the second current sense ampli- fier using the VSENSE2+ and VSENSE2- test points as the inputs and VOUT2 test point as the output. 19-7021; Rev 0; 7/14 Ordering Information appears at end of data sheet. |
