Evaluates: MAX16141 MAX16141 Evaluation Kit MAX16141A General Description Quick Start The MAX16141 evaluation kit (EV kit) evaluates Required Equipment the MAX16141/MAX16141A. The MAX16141 is a MAX16141 EV kit diode controller and protection device that protects 40V, 10A DC power supply systems against fault conditions, such as reverse-current, overcurrent, input overvoltage/undervoltage, short-circuit, One digital multimeter (DMM) and overtemperature. The MAX16141 EV kit comes Procedure with the MAX16141AAF/V+ IC installed. The MAX16141 The EV kit is fully assembled and tested. Follow the steps EV kit undervoltage/overvoltage thresholds are set to below to verify board operation. 8.6V/36.2V, respectively. Caution: Do not turn on power supply until all connections Features are completed. 8.6V to 36.2V Undervoltage/Overvoltage Thresholds 1) Verify that shunts are installed onto their respective Output Short-Circuit Protection default positions for jumpers JU1JU3 (Table 1, Table 2, and Table 3).

Fully Assembled and Tested 5) Manually sweep the power supply from 8.6V to 36.2V. Verify that the output voltage at OUT MAX16141 EV Kit Files approximately follows the input voltage at IN. 6) Increase the input voltage to 37V. FILE DECRIPTION 7) Verify that the output voltage is 0V (overvoltage MAX16141 EV BOM EV Kit Bill of Material protection) MAX16141 EV PCB Layout EV Kit Layout 8) Set the input voltage to 12V and verify that OUT is also about 12V. MAX16141 EV Schematic EV Kit Schematic 9) Using an insulated shorting cable, take caution to hold the insulated parts of the shorting cable while shorting OUT to SYSGND, and verify that the output voltage is 0V (Short circuit protection). Ordering Information appears at end of data sheet. 10) Remove the shorting cable between OUT and SYSGND and verify that the output voltage is 12V. 11) Decrease the input voltage to 7V. 12) Verify that the output voltage is approximately 0V (undervoltage protection). 319-100230 Rev 1 12/19Evaluates: MAX16141 MAX16141 Evaluation Kit MAX16141A Overvoltage Protection Detailed Description of Hardware The MAX16141 EV kit shuts down the output when the The MAX16141 EV kit evaluates the MAX16141 IC.
