CC6904SO-10A from Cross chip, 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	IP+	passive	Primary current sense input, positive terminal. Tie together with pin 2 as the current-carrying primary conductor entering the sensor (Rp ≈ 1.5 mΩ). Isolated from the signal side by 2000 VAC.
2	IP+	passive	Primary current sense input, positive terminal (paralleled with pin 1). Carries the sensed load current into the internal primary conductor.
3	IP-	passive	Primary current sense input, negative terminal. Tie together with pin 4 as the return side of the primary current path.
4	IP-	passive	Primary current sense input, negative terminal (paralleled with pin 3). Return leg of the sensed primary current.
5	GND	power_in	Signal-side ground reference for VCC and OUT. Connect to system ground with a local decoupling network.
6	NC	unconnected	No connect. Datasheet states this pin must be left floating (需悬空); do not tie to any net.
7	OUT	output	Analog output. Ratiometric voltage centered at VCC/2 (1.635-1.665 V at VCC = 3.3 V) with 132 mV/A slope for the -10A variant, swinging 0.33-2.97 V over the ±10 A input range. Source capability 400 µA, sink 30 mA; typical load ≥20 kΩ and ≤1 nF.
8	VCC	power_in	Supply voltage input. Recommended operating range 3.0-3.6 V (absolute max 7 V). Quiescent current ≈5 mA (8 mA max). Decouple with a 0.1 µF ceramic to GND close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6904so-10a.step`	122 KB	You want the bare part, or you mark your own boards.
`cc6904so-10a-etched.step`	2.6 MB	You want the part with `CC6904SO-10A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 616 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.
