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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `CC6920BSO-5ABSO-5A`+- `CC6920BSO-5ABSO-2.5A`+- `CC6920BSO-5ABSO-10A`+- `CC6920BSO-5ABSO-20A`+- `CC6920BSO-5ABSO-25A`+- `CC6920BSO-5ABSO-30A`+- `CC6920BSO-5ABSO-40A`+- `CC6920BSO-5ABSO-50A`+- `CC6920BSO-5ASO-XXA`++## CAD (KiCad official)++- Symbol: `CC6920BSO-5A`+- 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-5a-datasheet.pdf) (23 pp, sha256 `bf0f27c31807521e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
