WXNSIC · Gate Drivers · SOIC-8
NSG4427 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 | NC | unconnected | No-connect pin (datasheet: 空引脚); leave it unconnected. |
| 2 | INA | input | Channel A logic input that accepts -10V to VCC+0.3V, with VIH minimum 2.4V and VIL maximum 0.8V, and is non-inverting to OUTA. |
| 3 | GND | power_in | Ground reference pin for all voltages and the common return for the driver; the datasheet notes it tolerates noise spikes up to 5V of either polarity. |
| 4 | INB | input | Channel B logic input that accepts -10V to VCC+0.3V, with VIH minimum 2.4V and VIL maximum 0.8V, and is non-inverting to OUTB. |
| 5 | OUTB | output | Channel B driver output, in phase with INB, sourcing or sinking a peak current of 2A. |
| 6 | VCC | power_in | Supply pin; the recommended operating range is 4.5V to 20V and the absolute maximum is 25V. |
| 7 | OUTA | output | Channel A driver output, in phase with INA, sourcing or sinking a peak current of 2A. |
| 8 | NC | unconnected | No-connect pin (datasheet: 空引脚); leave it unconnected. |
