Pin Functions

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.
