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).
Supports sleep-mode charging for most available apple devices and/or BC1.2 compliant devices
