XJNG2102 from Wuxi NCE Power Semiconductor, in a SOIC-8. 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.
