7 VREG vs CDP_ENZ Pins

In TUSB212 the VREG pin requires a 0.1-µF external capacitor to GND to stabilize the 1.8V core. When using TUSB216I, the external capacitor is no longer required. It is still acceptable, however, to connect the external capacitor to the CDP_ENZ pin.

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, and TUSB216I's internal 500 kΩ pull-up will disable the BC1.2 controller. To enable BC1.2 CDP mode, use a 10 kΩ pull-down resistor to GND. TUSB216I's CDP_ENZ is sampled after Power-On Reset or de-assertion of the RSTN pin.
