NSG21275 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 | VCC | power_in | Low-side supply pin, recommended 8 V to 20 V with respect to VSS (absolute maximum -0.3 V to 22 V). |
| 2 | IN | input | Logic input in phase with HO, with VIH minimum 2.5 V, VIL maximum 0.8 V (VCC = 10 V to 20 V), and input range 0 V to VCC. |
| 3 | FAULT | output | Overcurrent shutdown report output with negative logic (open-drain style, low-level on-resistance typically 125 Ω), with voltage range 0 V to VCC. |
| 4 | VSS | power_in | Ground reference for the low-side circuit; all voltage ratings are referenced to VSS. |
| 5 | VS | power_in | High-side floating ground reference, recommended -5 V to 300 V, and tolerates transient negative VS down to VSS-50 V for 50 ns pulses. |
| 6 | CS | input | Overcurrent detection input with positive-going threshold of 1.7 V to 1.9 V (typical 1.8 V), recommended range VS to VS+5 V. |
| 7 | HO | output | High-side gate driver output, swinging between VS and VB, with typical source and sink current of 1.5 A (minimum 1.2 A, pulse width up to 10 µs). |
| 8 | VB | power_in | High-side floating supply, recommended VS+8 V to VS+20 V, with UVLO thresholds of 6.8 V (falling) and 7.2 V (rising) typical. |
