In the TUSB211, the VREG pin required a 0.1-µF external capacitor to GND to stabilize the core. When using the TUSB216I, the external capacitor used for the VREG pin of the TUSB211, is not required. It is still acceptable to connect the external capacitor to the CDP_ENZ pin. The TUSB216I includes an optional feature to enable an internal BC1.2 CDP controller for battery charging applications. If not required this pin can be left unconnected, the internal 500 kΩ pullup of the TUSB216I disables the BC1.2 controller. To enable BC1.2 CDP mode, use a 10-kΩ pulldown resistor to GND. The CDP_ENZ is sampled at reset.
