AO4466 from UMW, in a SOP-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 | S | passive | Source terminal; pins 1, 2 and 3 are all source leads, separated so a Kelvin connection can bypass source inductance. |
| 2 | S | passive | Source terminal; pins 1, 2 and 3 are all source leads, separated so a Kelvin connection can bypass source inductance. |
| 3 | S | passive | Source terminal; pins 1, 2 and 3 are all source leads, separated so a Kelvin connection can bypass source inductance. |
| 4 | G | input | Gate terminal of the N-channel MOSFET; the absolute maximum gate-source voltage is ±20 V. |
| 5 | D | passive | Drain terminal; pins 5 to 8 are the common drain, with a drain-source voltage rating of 30 V. |
| 6 | D | passive | Drain terminal; pins 5 to 8 are the common drain, with a drain-source voltage rating of 30 V. |
| 7 | D | passive | Drain terminal; pins 5 to 8 are the common drain, with a drain-source voltage rating of 30 V. |
| 8 | D | passive | Drain terminal; pins 5 to 8 are the common drain, with a drain-source voltage rating of 30 V. |
