CC6900SO-30A 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 sampled current positive terminal. Tied internally to pin 2 as one end of the low-impedance primary current conductor. 100 V isolation to signal-side pins.
2	IP+	passive	Primary sampled current positive terminal (paralleled with pin 1). Part of the internal low-impedance primary conductor whose magnetic field is sensed by the on-die Hall element.
3	IP-	passive	Primary sampled current negative terminal. Tied internally to pin 4 as the return end of the primary current conductor.
4	IP-	passive	Primary sampled current negative terminal (paralleled with pin 3).
5	GND	power_in	Signal-side ground reference for the internal Hall amplifier and output stage.
6	NC	unconnected	No connect. Datasheet specifies this pin must be left floating (需悬空).
7	OUT	output	Analog signal output. Quiescent output = 50% VCC in zero magnetic field; swings linearly from 0.5 V to 4.5 V at VCC = 5 V. For the -30A variant, sensitivity is 67 mV/A.
8	VCC	power_in	Supply voltage input, nominal 5 V. Powers the Hall front-end, chopper-stabilized amplifier, oscillator and output driver.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6900so-30a.step`	122 KB	You want the bare part, or you mark your own boards.
`cc6900so-30a-etched.step`	2.9 MB	You want the part with `CC6900SO-30A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 675 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.
