NSG4427

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.
