USB2.0 data lines from Type A connector J9 are connected to the USB1 interface of the AM62x 17x17 SOC to provide USB high-speed/full-speed communication. USB1_VBUS to the SOC is provided through a resistor divider network to support (5V-30V) VBUS operation. USB1_DRVVBUS from SOC is connected to the enable pin of Load switch (manufacturer part number: TPD3S014DBVR) to allow on board 5V supply to power the VBUS..
A common mode choke of DLW21SZ900HQ2B is provided on USB Data lines to take care of EMI/ EMC.
USB Data lines from Type-A connectors are also connected to the current limit load switch and ESD Protection IC (manufacturer part number: TPD3S014DBVR). This switch limits the current to 500mA and dissipates the ESD strikes above the maximum level specified in the IEC 61000-4-2.
