BCT4227ETB-TR from BROADCHIP, in a WQFN-10(1.4x1.8). 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 | D+ | passive | Data port D+ is a switch terminal that the datasheet limits to GND to 4.2 V in recommended operating conditions, with an absolute maximum of -0.5 to +5.25 V. |
| 2 | D- | passive | Data port D- is a switch terminal that the datasheet limits to GND to 4.2 V in recommended operating conditions, with an absolute maximum of -0.5 to +5.25 V. |
| 3 | GND | power_in | Ground reference pin for the device. |
| 4 | HSD1- | passive | High-speed data port 1 negative terminal, with analog signal range from GND to VCC. |
| 5 | HSD1+ | passive | High-speed data port 1 positive terminal, with analog signal range from GND to VCC. |
| 6 | HSD2- | passive | High-speed data port 2 negative terminal, with analog signal range from GND to VCC. |
| 7 | HSD2+ | passive | High-speed data port 2 positive terminal, with analog signal range from GND to VCC. |
| 8 | /OE | input | Active-low output enable; when high both channels are OFF, and the input requires VIH of at least 1.6 V and VIL of at most 0.5 V at VCC = 3.6 V, with an input range of GND to VCC. |
| 9 | VCC | power_in | Positive power supply, specified from 1.65 V to 4.5 V, with an absolute maximum of 5.25 V. |
| 10 | SEL | input | Select input that, with /OE low, connects HSD1 when low (SEL = 0) and HSD2 when high (SEL = 1). |
