TPS2540RTET

The TPS2540RTET is an USB charging port Power Switch and Controller with an USB 2.0 high-speed data line (D+/D-) switch and an USB charging port identification circuit. Applications include notebook PCs and other intelligent USB host devices. 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 monitor D+ and D-, providing the correct hand-shaking protocol with compliant client devices. This charge mode allows the host device to actively select between Dedicated Charging Port (DCP) (wall-adapter emulation), Charging Downstream Port (CDP) (active USB 2.0 data communications with 1.5A support) or Standard Downstream Port (SDP) USB 2.0 Mode (active USB 2.0 data communications with 500mA support).
