DESCRIPTION
The TPS2540/40A and TPS2541/41A are 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.
Applications include notebook PCs and other
intelligent USB host devices. The wide bandwidth (2.6
GHz) data-line switch also features low capacitance
and low on resistance, allowing signals to pass with
minimum edge and phase distortion. The
TPS2540/40A/41/41A monitors D+ and D-, providing
the correct hand-shaking protocol with compliant
client devices.
The TPS2540/40A/41/41A supports the following
charging logic schemes:
USB 2.0 BC1.2
Chinese Telecom Standard YD/T 1591-2009
Divider Mode, compliant with Apple devices such
as iPod® and iPhone®
CTL1-CTL3 logic inputs are used to select one of the
various charge modes provided by the TPS2540/40A
and TPS2541/41A. These charge modes allow 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 1.5-A support), or
Standard Downstream Port (SDP) USB 2.0 Mode
(active USB 2.0 data communications with 500-mA
support). The TPS2540/40A/41/41A also integrates
an auto-detect feature that supports both DCP
schemes for Battery Charging Specification (BC1.2)
and the Divider Mode without the need for outside
user interaction.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
DESCRIPTION (CONT.)
The TPS2540A/41A auto detect mode also has a longer detach detection time, so that it can support certain
unique non-compliant devices. The TPS2540/40A/41/41A power-distribution switch is intended for applications
where heavy capacitive loads and short-circuits are likely to be encountered, incorporating a 73-mΩ, N-channel
MOSFET in a single package. Constant-current mode is used when the output load exceeds the current-limit
threshold. ILIM_SEL logic input selects one of two current-limit thresholds, each one being individually adjustable
via an external resistor. Additional USB switch features include a de-glitched output fault reporting (FAULT), and
a logic-level enable EN (TPS2540/40A) or OUT discharge control DSC (TPS2541/41A). With the TPS2540/40A,
the mode 000is used to force an output discharge.
