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). Pins 1 and 2 are internally tied together and form one terminal of the isolated primary copper conductor (~0.9 mΩ). Positive current flow from IP+ (pins 1-2) to IP- (pins 3-4) produces a positive sensor output. |+| 2 | IP+ | passive | Current Sampled + (primary conductor input). Internally connected to pin 1 to form the positive terminal of the primary current path. Continuous current rating 40 A; peak 100 A (3 s). |+| 3 | IP- | passive | Current Sampled - (primary conductor return). Pins 3 and 4 are internally tied together and form the return terminal of the isolated primary copper conductor. |+| 4 | IP- | passive | Current Sampled - (primary conductor return). Internally connected to pin 3 to form the negative terminal of the primary current path. |+| 5 | GND | power_in | Signal ground reference for the secondary (signal) side of the isolation barrier. All output voltages (OUT, VZCR) and VCC are referenced to this pin. |+| 6 | VZCR | output | Zero-current reference signal output (VCC/2). Provides a ratiometric mid-supply reference for downstream signal-conditioning circuits. Source current ≤400 µA, sink current ≤3 mA; recommend reserving ≥0.3 mA in design. |+| 7 | OUT | output | Analog voltage output proportional to the sensed primary current. VOUT = VCC/2 + 0.200 × IP(A) for the -10A variant (200 mV/A sensitivity). Guaranteed linear range 0.5 V to 4.5 V at VCC = 5 V; drives up to 6 mA source / 30 mA sink into a load of ≥1.5 kΩ and ≤1 nF. |+| 8 | VCC | power_in | Power supply for the signal side of the chip. Recommended operating range 4.5 V to 5.5 V; absolute max 7 V. Typical supply current 20 mA. Decouple with 0.1 µF to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `CC6920SO-10A`+- `CC6920SO-10ACC6920SO-2.5A`+- `CC6920SO-10ACC6920SO-5A`+- `CC6920SO-10ACC6920SO-20A`+- `CC6920SO-10ACC6920SO-25A`+- `CC6920SO-10ACC6920SO-30A`+- `CC6920SO-10ACC6920SO-40A`+- `CC6920SO-10ACC6920SO-50A`+- `CC6920SO-10ACC6920SO-XXA`++## CAD (KiCad official)++- Symbol: `CC6920SO-10A`+- 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/cc6920so-10a-datasheet.pdf) (23 pp, sha256 `5fe4aa3fee763407`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
