Passing the IEC 61000-4-2 test for DP_IN and DM_IN requires connecting a discharge resistor to OUT during
USB 2.0 high-speed enumeration. In client mode, because the power switch is OFF, OUT must be 5 V so that
the device can work normally (usually powered by an external downstream USB port). If the OUT voltage is low,
the communication may not work properly.
8.4.6 High-Bandwidth Data-Line Switch
The D+ and D– data lines pass through the device to enable monitoring and handshaking while supporting the
charging operation. A wide-bandwidth signal switch allows data to pass through the device without corrupting
signal integrity. The data-line switches are turned on in any of the CDP, SDP or client operating modes. The EN
input must be at logic high for the data-line switches to be enabled.
NOTE
While in CDP mode, the data switches are ON, even during CDP handshaking.
The data switches are only for the USB-2.0 differential pair. 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 TPS254900A-Q1 device.
Data switches are OFF during OUT (VBUS) discharge.
