APPLICATION INFORMATION

The TPS2513 and TPS2514 only provide the correct electrical signatures on the data line of USB charger port

and do not provide any power for the VBUS.

Divide Mode Selection of 5-W and 10-W USB Chargers

The TPS2513 and TPS2514 provide two types of connections between the DP pin and the DM pin and between

the D+ data line and the D– data line of the USB connector for a 5-W USB charger and a 10-W USB charger

with a single USB port. For 5-W USB charger, the DP1 pin is connected to the D– line and the DM1 pin is

connected to the D+ line. This is shown in Figure 13. For 10-W USB charger, the DP1 pin is connected to the D+

line and the DM1 pin is connected to the D– line. This is shown in Figure 14. Table 4 shows different charging

schemes for both 5-W and 10-W USB charger solutions. DP2 and DM2 of TPS2513 also provides this two types

of connections.
