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 + input. One terminal of the internal low-resistance (~0.9 mΩ) copper primary conductor. Pins 1 and 2 are internally connected and should be tied together on the PCB to carry the sensed current (up to ±30 A continuous for this variant). |+| 2 | IP+ | passive | Current sampled + input. Internally connected to pin 1; both pins form the positive terminal of the isolated primary copper conduction path. |+| 3 | IP- | passive | Current sampled - input. One terminal of the internal low-resistance copper primary conductor. Pins 3 and 4 are internally connected and should be tied together on the PCB. |+| 4 | IP- | passive | Current sampled - input. Internally connected to pin 3; both pins form the negative terminal of the isolated primary copper conduction path. |+| 5 | GND | power_in | Signal-side ground reference for the secondary circuitry. All VOUT and VZCR voltages are referenced to this pin. |+| 6 | VZCR | output | Zero current reference signal output. Nominally VCC/2 (≈1.65 V at VCC=3.3 V), used as a ratiometric zero-current baseline for downstream ADCs or differential amplifiers. Source current up to 400 µA; sink current up to 3 mA. |+| 7 | OUT | output | Analog voltage output proportional to sensed primary current. VOUT = VCC/2 + 0.044 × IP (V) for the 30 A variant. Linear range 0.33-2.97 V at VCC=3.3 V; source 6 mA / sink 30 mA max. |+| 8 | VCC | power_in | Signal-side supply voltage input. Operating range 3.0-3.6 V (typ 3.3 V); typical ICC = 20 mA (25 mA max) with OUT floating. Absolute max 7 V. Decouple with 0.1 µF to GND close to pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `CC6920BSO-30A`+- `CC6920BSO-2.5A`+- `CC6920BSO-5A`+- `CC6920BSO-10A`+- `CC6920BSO-20A`+- `CC6920BSO-25A`+- `CC6920BSO-40A`+- `CC6920BSO-50A`+- `CC6920SO-XXA`++## CAD (KiCad official)++- Symbol: `CC6920BSO-30A`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Cross chip datasheet](docs/cc6920bso-30a-datasheet.pdf) (23 pp, sha256 `bf0f27c31807521e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
