Pin Functions

PIN I/O DESCRIPTION
NAME NUMBER
FAULT 1 O Fault event indicator. Open-drain logic output that asserts low to indicate current limit or thermal shutdown event due to over temperature.
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.
AUX 5 I Auxiliary input supply. Connect to always alive system rail to use the Power Wake feature. Short to IN1 and IN2 if only one supply is used.
EN 6 I Enable logic input to turn the device on and off.
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 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.
REF_RTN 9 I Precision signal reference return. Connect to REF pin via 100-kΩ, 1% resistor.
REF 10 I Analog input used to generate internal current reference. Connect a 1% or better, 100 ppm, 100-kΩ resistor between this pin and REF_RTN.
CC1 11 I/O Analog input/output that connects to the Type-C receptacle CC1 pin
GND 12 – Power ground
CC2 13 I/O Analog input/output that connects to the Type-C receptacle CC2 pin.
OUT 14,15 O Power switch output.
DEBUG 16 O Open-drain logic output that asserts when a Type-C Debug accessory is identified on the CC lines.
AUDIO 17 O Open-drain logic output that asserts when a Type-C Audio accessory is identified on the CC lines.
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 mux the super speed lines. Asserted when the CC2 pin is connected to the CC line in cable.
UFP 19 O Open-drain logic output that asserts when a Type-C UFP is identified on the CC lines.
LD_DET 20 O Load-detect open-drain logic output that signals when a device set to source Type-C 3 A current is sourcing over 1.95 A nominal.
Thermal Pad – – Thermal pad on bottom of package.
