Product Overview

The TPS2540EVM-623 is a fully assembled and tested evaluation module for TPS2540 USB Charging Port Power Switch and Controller. The board also supports for TPS2540A/41/41A family of devices. The TPS2540 is a combination of current limited USB port power switch with a USB 2.0 high speed data line (D+/D-) switch and a USB charging port identification circuit. The wide bandwidth (2.6GHz) data line switch also features low capacitance and low on resistance, allowing signals to pass with minimum edge and phase distortion. The TPS2540 monitors D+ and D-, providing the correct hand shaking protocol with compliant client device. CTL1-CTL3 logic inputs are used to select one of the various charge modes provided by the TPS2540. These charge modes allow the host device to actively select between Dedicated Charging Port (wall adapter emulation), charging downstream port (active USB 2.0 data communications with 1.5A support), or Standard Downstream Port USB 2.0 Mode.
