9.3.8 BC 1.2, Legacy and Fast Charging Modes (Px_DP, Px_DM)
BC 1.2 downstream port charger emulation is application GUI configurable. The following charging modes can be enabled or disabled:
- DCP (Dedicated Charging Port) Shorted Mode
- Divider-3 Mode
- 1.2-V Mode
- HVDCP (High Voltage Dedicated Charging Port) Mode
The following table shows voltage sources, resistors and comparator hardware used in each mode. Symbol "X" represents that the corresponding module is implemented.
