9 Applications and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The TPS251xx devices are USB dedicated charging port. The devices only provide the correct electrical

signatures on the data lines of USB charger port and do not provide any power for the VBUS. Below is typical

applications for USB charging ports.

9.2.2 Detailed Design Procedure

9.2.2.1 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 16. 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 17. 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.
