Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VCC | power_in | Low side and main power supply. Recommended 6 V to 20 V (abs max 25 V) referenced to COM. Provides the low-side gate-drive rail and powers the internal logic. |+| 2 | HIN | input | Logic input for high-side gate driver output (HO). CMOS/LSTTL compatible down to 3.3 V logic; VIH >= 2.5 V, VIL <= 0.8 V. HO is in phase with HIN. |+| 3 | LIN | input | Logic input for low-side gate driver output (LO). CMOS/LSTTL compatible down to 3.3 V logic; VIH >= 2.5 V, VIL <= 0.8 V. LO is out of phase with LIN (inverting). |+| 4 | COM | power_in | Device ground / low-side return. All absolute voltage parameters are referenced to COM. |+| 5 | LO | output | Low-side gate drive output. Swings between COM and VCC with typical 1 A source / 1 A sink pulsed capability; drives the gate of the low-side N-channel power MOSFET. |+| 6 | VS | power_in | High-side floating supply return / bootstrap return. Connects to the source of the high-side MOSFET and the negative terminal of the bootstrap capacitor. Rated -6 V to +200 V (abs max VB-25 to VB+0.3), dV/dt tolerance up to 50 V/ns. |+| 7 | HO | output | High-side gate drive output, in phase with HIN. Swings between VS and VB with typical 1 A source / 1 A sink pulsed capability; drives the gate of the high-side N-channel power MOSFET. |+| 8 | VB | power_in | High-side floating supply (bootstrap supply positive rail). Recommended VS+6 V to VS+20 V (abs max 225 V to COM). Connects to the positive terminal of the bootstrap capacitor and cathode of the bootstrap diode. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Wuxi NCE Power Semiconductor |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `XJNG2102`++## CAD (KiCad official)++- Symbol: `XJNG2102`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Wuxi NCE Power Semiconductor datasheet](docs/xjng2102-datasheet.pdf) (6 pp, sha256 `e3ae5b7b069d531a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
