SLVSBA6 FEBRUARY 2012
DCP Forced Shorted / DCP Forced Divider 1
In this mode the device is permanently set to one of the DCP schemes (BC 1.2/ YD/T 1591-2009 or Divider 1) as
commanded by its control pin setting per device truth table.
High-Bandwidth Data Line Switch
The TPS2543 passes the D+ and D- data lines through the device to enable monitoring and handshaking while
supporting charging operation. A wide bandwidth signal switch is used, allowing data to pass through the device
without corrupting signal integrity. The data line switches are turned on in any of CDP or SDP operating modes.
The EN input also needs to be at logic High for the data line switches to be enabled.
NOTE
1. While in CDP mode, the data switches are ON even while CDP handshaking is occurring.
2. The data line switches are OFF if EN or all CTL pins are held low, or if in DCP mode. They are not
automatically turned off if the power switch (IN to OUT) is in current limit.
3. The data switches are for USB 2.0 differential pair only. In the case of a USB 3.0 host, the super speed
differential pairs must be routed directly to the USB connector without passing through the TPS2543.
