L = Default (pull-down to GND or leave unconnected); M = Medium 1.5 A (pull-up to VDD via 500-kΩ resistor); H = High 3.0 A (pull-up to VDD via 10-kΩ resistor). VDD must be ≥3.5 V to advertise 3 A.

H = DFP (pull-up to VDD); NC = DRP (leave open or tie via 4.7 kΩ); L = UFP (pull-down or tie to GND). Internal R_pu ≈ 588 kΩ, R_pd ≈ 1.1 MΩ. [datasheet p.3] |-| 5 | VBUS_DET | input | VBUS detection input, 5 V to 28 V input range (abs max -0.3 V to 4 V at the pin). VBUS detection determines UFP attachment. One external R_VBUS resistor is required between system VBUS and this pin; threshold on the pin ≤4 V. [datasheet p.3] |-| 6 | ~{VCONN_FAULT} | open_collector | Active-low open-drain fault output.

[datasheet p.3] |+| 1 | CC1 | bidirectional | USB Type-C Configuration Channel signal 1. Internal pull-ups/pull-downs (Rp or Rd ≈ 5.1 kΩ) select DFP/UFP role and detect cable attach, orientation, and advertised current. [datasheet p.3] |+| 2 | CC2 | bidirectional | USB Type-C Configuration Channel signal 2. Mirror of CC1 for the other CC line in the Type-C receptacle; used together with CC1 to determine plug orientation.

Internal 95 kΩ pulldown forms a divider; the VBUS_THR threshold is ~3.3 V at the pin and determines UFP attach.
