HUSB238 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; all signal references are to this pin.
Pin 1 (VIN) requires a 1μF ceramic capacitor to GND for decoupling.
Pins 8 (VSET) and 9 (ISET) have internal 100μA source current for resistor-based configuration.
Pin 10 (GATE) is an open-drain output suitable for driving a FET gate through a series resistor.
