HUSB305-01 from Hynetek, in a TSOT-23-8L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Input pin to the power switch and internal circuit, with UVLO rising threshold of 3.8 V and an input voltage range of 3 V to 6.5 V. |
| 2 | GND | power_in | Ground plane to which all signals are referred. |
| 3 | ISET | input | Sets the constant-current limit by a resistor to GND: 150 kΩ gives 3.6 A, 200 kΩ gives 2.8 A, and 348 kΩ gives 1.8 A, with the HUSB305 trimmed at 3.6 A. |
| 4 | NC | unconnected | Not connected pin. |
| 5 | CC2 | passive | Configuration line 2 of the USB Type-C connector, which sources the Rp current (180/330 µA) and is monitored for Sink attachment; absolute maximum −0.3 V to +7 V to GND. |
| 6 | CC1 | passive | Configuration line 1 of the USB Type-C connector, which sources the Rp current (180/330 µA) and is monitored for Sink attachment; absolute maximum −0.3 V to +7 V to GND. |
| 7 | STAT | output | Open-drain output that in HUSB305-01 is high-impedance when load current is above ILLD (40 mA at VIN = 5 V) and pulled low when below it, with a 4 mA sink current when low. |
| 8 | VBUS | power_out | Output of the internal power FET (15 mΩ typical RDSON) connected to the USB Type-C port, with a 7 V absolute maximum to GND. |
