CC6900SO-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	Positive terminal of the sampled current path (primary conductor input). Tied internally to pin 2. Isolated from the signal pins by 100 V.
2	IP+	passive	Positive terminal of the sampled current path (primary conductor input). Tied internally to pin 1.
3	IP-	passive	Negative terminal of the sampled current path (primary conductor output). Tied internally to pin 4.
4	IP-	passive	Negative terminal of the sampled current path (primary conductor output). Tied internally to pin 3.
5	GND	power_in	Signal ground / device ground reference. Isolated from the IP+/IP- current path by 100 V.
6	NC	unconnected	No connect. Datasheet specifies this pin must be left floating (需悬空).
7	OUT	output	Single-ended analog output. Quiescent (zero-field) output is 50% VCC; swings 0.5 V to 4.5 V at VCC = 5 V, ratiometric with the sensed current at 200 mV/A for the 10 A variant.
8	VCC	power_in	Supply voltage input, nominally 5 V. Sets the ratiometric output range (0.5 V to 4.5 V typical at VCC = 5 V).

CAD (KiCad official)

Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
3D model: SOP-8 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6900so-10a.step`	122 KB	You want the bare part, or you mark your own boards.
`cc6900so-10a-etched.step`	2.7 MB	You want the part with `CC6900SO-10A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 639 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.
