General Description 5) Write 0 to FM ENb (0x01 bit1). The MAX20330A evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the 6) Connect a 150k resistor between ID TP22 and MAX20330A HV-capable ID detection device. The EV kit ground. comes with the MAX20330AEWA+ installed. 7) Check that register 0x09 is 00001000 (ID resistor is in factory mode range). Features 8) Connect 3V to ID. Verify that VBAT is now also 3V. USB or 3.5mm Jack ID Detection Factory Mode Detection Detailed Description Proven PCB Layout The MAX20330A EV kit is a fully assembled and tested circuit board demonstrating the MAX20330A ID detector Fully Assembled and Tested in an 8-bump wafer-level package (WLP). EV Kit Contents V Power Supply CC EV Kit Board Containing a MAX20330A The V can be connected from different power supply CC sources or externally supplied from TP12. (Table 1) Quick Start USB/Audio ID Detection Required Equipment The EV kit can be configured for USB micro-B or 3.5mm MAX20330A EVKIT Jack ID detection. (Table 2) Power supply 2 I C Communication 2 2 I C master Use JU5, JU6, JU7, JU8, and JU9 to have I C pins pulled 2 up to selected supply. User needs to provide I C master 150k resistor to communicate with the device. The slave address is Multimeter 1010 111. (Table 3) Procedure Enable The EV kit is fully assembled and tested. Follow the steps Use JU10 to enable the device. For USB configuration, below to verify board operation: the user can use external test point TP11 to enable the 1) Connect a 5V power supply on VCC TP12. Check device or install shunts on JU3 and JU10. (Table 4) that LED1 is on. 2 2) Connect an I C master to SDA and SCL on the EV kit. The device slave address is 1010111. Ordering Information appears at end of data sheet. 3) Remove the JU4 shunt, install the shunt on JU10. Check OVLO ENb (0x02 bit0) is 1. The device is enabled. 319-100251 Rev 1 2/19MAX20330A Evaluation Kit Evaluates: MAX20330A Table 1.
