FL73282MX from onsemi, 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-side supply voltage, recommended 10 V to 20 V (absolute maximum 24 V).
2	HIN	input	Logic input for the high-side gate driver output, with Logic 1 threshold of 2.5 V min and Logic 0 of 0.8 V max, referenced to COM.
3	LIN	input	Logic input for the low-side gate driver output, with Logic 1 threshold of 2.5 V min and Logic 0 of 0.8 V max, referenced to COM.
4	COM	power_in	Logic ground and low-side driver return.
5	LO	output	Low-side driver output, typically sourcing 350 mA and sinking 650 mA, swinging between COM and VCC.
6	VS	power_in	High-voltage floating supply return, operating offset up to 900 V and allowable negative swing to -9.8 V typical.
7	HO	output	High-side driver output, typically sourcing 350 mA and sinking 650 mA, swinging between VS and VB.
8	VB	power_in	High-side floating supply, recommended VS+10 V to VS+20 V (absolute maximum 924 V).
