PRODUCTION DATA.
| PIN | I/O | DESCRIPTION | ||
|---|---|---|---|---|
| NAME | NO. | |||
| AUDIO | 17 | O | Open-drain logic output that asserts when a Type-C audio accessory is identified on the CC lines | |
| AUX | 5 | I | Auxiliary input supply. Connect to an always-alive system rail to use the power-wake feature. Short to IN1 and IN2 if only one supply is used. | |
| CC1 | 11 | I/O | Analog input/output that connects to the Type-C receptacle CC1 pin | |
| CC2 | 13 | I/O | Analog input/output that connects to the Type-C receptacle CC2 pin. | |
| CHG | 7 | I | Charge-logic input to select between standard USB (500 mA for a Type-C receptacle supporting only USB 2.0, and 900 mA for Type-C receptacle supporting USB 3.1) or a Type-C current-sourcing ability. | |
| CHG_HI | 8 | I | High-charge logic input to select between 1.5-A and 3-A Type-C current sourcing capability. Valid when CHG is set to Type-C current. | |
| CS | 20 | O | Open-drain output enabling digital cable compensation when load current is greater than 1.95 A, nominal. | |
| DEBUG | 16 | O | Open-drain logic output that asserts when a Type-C debug accessory is identified on the CC lines | |
| EN | 6 | I | Enable logic input. Turns the device on and off | |
| FAULT | 1 | O | Fault event indicator. Open-drain logic output that asserts low to indicate a current-limit or thermal-shutdown event due to overtemperature. | |
| GND | 12 | — | Power ground | |
| IN1 | 2, 3 | I | VBUS input supply. Internal power switch connects IN1 to OUT. | |
| IN2 | 4 | I | VCONN input supply. Internal power switch connects IN2 to CC1 or CC2. Short to IN1 if only one supply is used. | |
| OUT | 14, 15 | O | Power switch output | |
| POL | 18 | O | Polarity open-drain logic output that signals which Type-C CC pin is connected to the CC line. This gives the information needed to multiplex the super-speed lines. Asserted when the CC2 pin is connected to the CC line in the cable. | |
| REF | 10 | I | Analog input used to generate the internal current reference. Connect a 1% or better, 100-ppm, 100-kΩ resistor between this pin and REF_RTN. | |
| REF_RTN | 9 | I | Precision signal-reference return. Connect to the REF pin via a 100-kΩ, 1% resistor. | |
| UFP | 19 | O | Open-drain logic output that asserts when a Type-C UFP is identified on the CC lines. | |
| Thermal pad | — | — | Thermal pad on the bottom of the package. The thermal pad is internally connected to GND and is used to heat-sink the device to the circuit board. Connect the thermal pad to the GND plane. | |
