PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | FAULT | O | Fault event indicator. Open-drain logic output that asserts low to indicate a current-limit or thermal-shutdown event due to overtemperature. |
2 | IN1 | I | VBUS input supply. Internal power switch connects IN1 to OUT. |
3 | IN1 | I | VBUS input supply. Internal power switch connects IN1 to OUT. |
4 | IN2 | I | VCONN input supply. Internal power switch connects IN2 to CC1 or CC2. Short to IN1 if only one supply is used. |
5 | AUX | 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. |
6 | EN | I | Enable logic input. Turns the device on and off |
7 | CHG | 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. |
8 | CHG_HI | 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. |
9 | REF_RTN | I | Precision signal-reference return. Connect to the REF pin via a 100-kΩ, 1% resistor. |
10 | REF | 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. |
11 | CC1 | I/O | Analog input/output that connects to the Type-C receptacle CC1 pin |
12 | GND | — | Power ground |
13 | CC2 | I/O | Analog input/output that connects to the Type-C receptacle CC2 pin. |
14 | OUT | O | Power switch output |
15 | OUT | O | Power switch output |
16 | DEBUG | O | Open-drain logic output that asserts when a Type-C debug accessory is identified on the CC lines. |
17 | AUDIO | O | Open-drain logic output that asserts when a Type-C audio accessory is identified on the CC lines. |
18 | POL | 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. |
19 | UFP | O | Open-drain logic output that asserts when a Type-C UFP is identified on the CC lines. |
20 | LD_DET | 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 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. |
