1 Introduction
The TPS2549Q1EVM-729 allows reference circuit evaluation of the TI TPS2549-Q1 automotive USB
charging port controller with integrated power switch and cable compensation. The TPS2549Q1EVM-729
provides the electrical signatures on DP_IN and DM_IN to support all current charging schemes. The
TPS2549Q1EVM-729 incorporates USB cable voltage drop compensation by linearly sensing the port
current and automatically adjusting the output voltage of the LM53603AQ to keep the cable end device
voltage within the normal operating range.
