**WXNSIC** · Gate Drivers · SOIC-8

NSG2000 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 | VCC | power_in | Low-voltage supply for the driver, recommended 5 V to 20 V with an absolute maximum of -0.3 V to 25 V, and VCC undervoltage lockout thresholds of 4.2 V rising and 4.0 V falling. |
| 2 | IN | input | Logic signal input compatible with 3.3 V, 5 V and 15 V logic, with VIH minimum 2.5 V and VIL maximum 0.8 V for VCC = 10 V to 20 V, and a logic input range of 0 V to VCC. |
| 3 | OSC | input | OSC input whose recommended operating voltage range is 0 V to VCC, with an absolute maximum of GND - 0.3 V to VCC + 0.3 V; the datasheet gives no further functional description for this pin. |
| 4 | GND | power_in | Ground reference for all voltage parameters in the datasheet, with ambient temperature 25 °C for the stated absolute maximum ratings. |
| 5 | OL | output | Low-side output whose voltage is rated from GND to VCC, with a typical low-level output voltage drop (VOL) of 0.02 V and maximum of 0.1 V. |
| 6 | TS | power_in | Floating ground of the high-side circuit, recommended to operate between -9 V and 250 V (TS must stay within -9 V to 250 V for normal operation), with a transient slew-rate limit of 50 V/ns. |
| 7 | OUT | output | High-side gate drive output that swings between TS and BST, rated at 290 mA source and 600 mA sink (peak, PW ≤ 10 µs), driving the external N-channel MOSFET gate. |
| 8 | BST | power_in | Floating high-side supply referenced to TS, recommended TS + 5 V to TS + 20 V, with an absolute maximum of -0.3 V to 275 V. |
