LDR6028 from Legendary, in a SOP-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	VSS	power_in	Chip ground reference.
2	ResetOut	output	Controls audio-chip power rail; directly drives the gate of an AO3401 P-channel MOSFET to switch VBUS/audio chip supply.
3	VBEN	output	VBUS enable output; drives an external switch/load-switch to gate VBUS delivery.
4	VDET0	input	VBUS detection input for CONN-B port; senses presence/level of downstream VBUS.
5	CC2	bidirectional	USB Type-C CC2 channel for CONN-A port; used for cable orientation detection and USB PD BMC communication.
6	CC1	bidirectional	USB Type-C CC1 channel for CONN-A port; used for cable orientation detection and USB PD BMC communication.
7	PDLDO	passive	Internal LDO output for USB PD communication; connect an external decoupling capacitor to this pin.
8	VDD	power_in	Chip supply voltage. Recommended operating range 3.3-5.0 V; absolute maximum 5.5 V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ldr6028.step`	122 KB	You want the bare part, or you mark your own boards.
`ldr6028-etched.step`	1.9 MB	You want the part with `LDR6028` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 451 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
