NSG4437 from WXNSIC, 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 | NC | unconnected | Pin 1 is a no-connect (空引脚) and is not bonded to any internal function. |
| 2 | INA | input | Channel A logic input with VIH minimum 2.4 V, VIL maximum 0.8 V, and an absolute range of -10 V to VCC+0.3 V; tie to GND when unused. |
| 3 | GND | power_in | Ground reference for all voltage parameters, which the datasheet specifies relative to GND. |
| 4 | INB | input | Channel B logic input with VIH minimum 2.4 V, VIL maximum 0.8 V, and an absolute range of -10 V to VCC+0.3 V; tie to GND when unused. |
| 5 | OUTB | output | Channel B gate-drive output, in phase with INB, that sources and sinks 2 A peak and withstands up to 0.5 A reverse current without latch-up. |
| 6 | VCC | power_in | Supply pin with recommended range 4.5 V to 20 V and absolute maximum 25 V referenced to GND. |
| 7 | OUTA | output | Channel A gate-drive output, in phase with INA, that sources and sinks 2 A peak and withstands up to 0.5 A reverse current without latch-up. |
| 8 | SD | input | Active-high shutdown input that forces both OUTA and OUTB low when high; it has an internal 100 kΩ pull-down to GND and may be left floating or tied to GND when unused. |
