CC6920BSO-5A 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	Current sampled + (primary conductor input). Tied to pin 2 internally; connect both pins 1 and 2 to the positive side of the sensed current path. Rated up to 40 A continuous and 100 A peak (3 s).
2	IP+	passive	Current sampled + (primary conductor input). Tied to pin 1 internally; connect both pins 1 and 2 to the positive side of the sensed current path.
3	IP-	passive	Current sampled - (primary conductor return). Tied to pin 4 internally; connect both pins 3 and 4 to the return side of the sensed current path. Basic working isolation to secondary is 424 VRMS with 3500 VRMS withstand.
4	IP-	passive	Current sampled - (primary conductor return). Tied to pin 3 internally; connect both pins 3 and 4 to the return side of the sensed current path.
5	GND	power_in	Signal ground reference for the secondary (Hall-sensor) circuitry. All output voltages (VOUT, VZCR) are referenced to this pin.
6	VZCR	output	Zero-current reference signal output, nominally VCC/2 (typ. 1.65 V at VCC=3.3 V). Can be used as a ratiometric reference for a downstream ADC or differential amplifier. Source capability ≤ 400 µA, sink ≤ 3 mA - keep load light.
7	OUT	output	Analog voltage output proportional to sensed primary current. Quiescent (IP=0) output is 50% VCC (1.65 V at VCC=3.3 V). For the -5A variant, sensitivity is typ. 264 mV/A and the linear output swing is 0.2 V to 4.8 V. Load: RL ≥ 1.5 kΩ, CL ≤ 1 nF; source ≤ 6 mA, sink ≤ 30 mA.
8	VCC	power_in	Power supply for the Hall sensor secondary circuit. Recommended 3.0-3.6 V (typ. 3.3 V); absolute max 7 V. Typical supply current ICC = 20 mA (max 25 mA) with OUT floated. Bypass with a 0.1 µF ceramic to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cc6920bso-5a.step`	122 KB	You want the bare part, or you mark your own boards.
`cc6920bso-5a-etched.step`	2.8 MB	You want the part with `CC6920BSO-5A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 651 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.
