BC1.2 charging is not supported in the TPS25820/21, however adding BC1.2 DCP (Dedicated Charging Port) support with the TPS25820/21 can be done by having the D+ and D- shorted together with a maximum impedance of 200 Ω between them and left floating with respect to ground. This is shown in Figure 19. However with DCP implementation the port will not support any data transfer, but is capable of advertising charge currents up to 1.5 A to a legacy device that is connected using a Type-C to Type-A or Micro-B cable. This type of port allows for wall chargers and car chargers with high-charge capability without the need for enumeration. Figure 19 shows a Type-C source implementation capable of supporting 5-V and 1.5-A charging in a Type-C port that is also able to support charging of legacy devices when used with a Type-C - μB cable assembly.
