NSG2186 from WXNSIC, in a SOIC-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 | HIN | input | High-side logic input, compatible with 3.3 V, 5 V and 15 V logic, with VIH minimum 2.5 V and VIL maximum 0.8 V. |
| 2 | LIN | input | Low-side logic input, compatible with 3.3 V, 5 V and 15 V logic, with VIH minimum 2.5 V and VIL maximum 0.8 V. |
| 3 | COM | power_in | Ground reference for the logic inputs and the low-side driver; the datasheet labels this pin 地 (ground). |
| 4 | LO | output | Low-side gate driver output, swinging between COM and VCC, with 4.0 A typical peak source/sink current (pulse width up to 10 µs). |
| 5 | VCC | power_in | Low-side supply, recommended 10 V to 20 V, with an absolute maximum of 25 V referenced to COM. |
| 6 | VS | power_in | High-side floating ground (offset return) for the high-side channel, recommended -9 V to 700 V, and tolerant of -9 V negative transients. |
| 7 | HO | output | High-side gate driver output, referenced to VS and swinging between VS and VB, with 4.0 A typical peak source/sink current (pulse width up to 10 µs). |
| 8 | VB | power_in | High-side floating supply, recommended VS + 10 V to VS + 20 V, with an absolute maximum of 725 V. |
