PI5USB2546A

DCP Forced Shorted / DCP Forced Divider-1A

In this mode the device is permanently set to one of the DCP schemes (BC1.2/ YD/T 1591-2009 or Divider-1A) as commanded

by its control pin setting per device truth table.

High-Bandwidth Data Line Switch

The PI5USB2546A series 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.

Under 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 PI5USB2546A series.

4.

Data switches are OFF during OUT (VBUS) discharge
