Evaluates: MAX20323/MAX20323A/ MAX20323 Evaluation Kit MAX20323B/MAX20323C/MAX20323D/ MAX20323E/MAX20323F General Description Quick Start The MAX20323 evaluation kit (EV kit) is a fully assembled Required Equipment and tested circuit board that demonstrates the MAX20323 MAX20323 EV kit USB type-C CC-pin overvoltage protection device. The 5V power supply or USB cable to power EV kit comes with the MAX20323ENC+ installed. The EV kit board can also be used to evaluate MAX20323A/ Power supply MAX20323B/MAX20323C/MAX20323D/MAX20323E/ Multimeter MAX20323F. Procedure Features The EV kit is fully assembled and tested. Follow the steps 2.5V to 5.5V Operating Voltage Range below to verify board operation: Power LED Reading 1) Connect a 5V power supply to TP14 or connect a USB cable to J3, verify LED1 is on. Proven PCB Layout 2) Check the voltage on JU1 pin2 is ~4.3V. Fully Assembled and Tested 3) Remove shunt on JU2, check the voltage on JU1 EV Kit Contents pin2 is ~2.5V. EV Kit Board Containing a MAX20323 4) Remove shunt on JU3, check the voltage on JU1 pin2 is ~1.257V. 5) Install shunt on JU2, check the voltage on JU1 pin2 Ordering Information appears at end of data sheet. is ~3.06V. 6) Install shunt on JU3 and JU1, check the voltage on TP11 is ~4.3V. 7) Connect another power supply 2V to TP3 CC1 I, check TP9 CC1 O is 2V. 8) Increase CC1 I voltage, when CC1 I reaches ~5.75V, CC1 O voltage drops down to ~5.1V. 9) Turn off the power supply on CC1 I, and connect the power supply to CC2 I TP4. 10) Set the power supply to CC2 I to 2V and check TP10 CC2 O is 2V. 11) Increase CC2 I voltage, when CC2 I reaches ~5.75V, CC2 O voltage drops down to ~5.1V. 319-100046 Rev 0 7/17Evaluates: MAX20323/MAX20323A/ MAX20323 Evaluation Kit MAX20323B/MAX20323C/MAX20323D/ MAX20323E/MAX20323F Table 1.
