SPRUJG2 December 2024 AM62D-Q1
USB2.0 Data lines DP and DM from Type-A connector J23 are connected to the USB1 interface of the AM62D 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 a 500mA current limited Load switch manufacturer part number TPS2051BD to allow on board 5V supply to power the VBUS. This load switch has an over current indication pin connected to I2C based GPIO expander on the EVM.
A common mode choke of manufacturer part number DLW21SZ900HQ2B is provided on USB Data lines for EMI/EMC reduction. Along with ESD Protection IC manufacturer part number TPD4S012DRYR to suppress any transient voltages.
