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. Table 4.
