Pin Configuration
HUSB238 – DFN-10L Pinout
| Pin | Name | Type | Description |
|---|---|---|---|
| 1 | VIN | P | Connect to VBUS of USB Type-C connector. Connect this pin to GND via a 1μF ceramic capacitor. |
| 2 | D+ | I/O | Positive line of USB 2.0 data line for Apple Divider 3 and BC1.2 |
| 3 | D- | I/O | Negative line of USB 2.0 data line for Apple Divider 3 and BC1.2 |
| 4 | CC1 | I/O | Configuration line 1 used to negotiate a voltage/current with the attached adapter |
| 5 | CC2 | I/O | Configuration line 2 used to negotiate a voltage/current with the attached adapter |
| 6 | SDA | I/O | I²C communication data signal |
| 7 | SCL | I/O | I²C communication clock signal |
| 8 | VSET | I | Connect a resistor to indicate the maximum voltage needed by the system from the attached power adapter. Internal 100μA source current is connected to this pin. |
| 9 | ISET | I | Connect a resistor to indicate the maximum current needed by the system from the attached power adapter. Internal 100μA source current is connected to this pin. |
| 10 | GATE | O | Open drain gate drive output. Connect this signal to the gate of a FET through a series resistor. This pin is the output of a PMOS FET gate driver. |
| 11 | GND | P | Ground plane. All signals are referred to this pin |
Notes:
- Pin 11 (GND) is the central ground plane shown in the package diagram.
- GATE (pin 10) is an open-drain output and requires external pull-up or series resistor to FET gate.
- VSET and ISET pins use internal 100μA source current for resistor-based configuration.
