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 current path positive terminal. Tie in parallel with pin 2 to carry the sampled current through the integrated low-impedance conductor. 100V isolation to signal pins. |+| 2 | IP+ | passive | Primary current path positive terminal (paralleled with pin 1). Part of the isolated current-carrying conductor. |+| 3 | IP- | passive | Primary current path negative/return terminal. Tie in parallel with pin 4. 100V isolation to signal pins. |+| 4 | IP- | passive | Primary current path negative/return terminal (paralleled with pin 3). |+| 5 | GND | power_in | Signal ground reference for the internal Hall front-end, chopper, and output amplifier. |+| 6 | NC | unconnected | No connection. Must be left floating per the datasheet (需悬空). |+| 7 | OUT | output | Analog signal output. Quiescent level = 0.5 x VCC (2.5V at VCC=5V); swings 0.5 V to 4.5 V linearly with sensed current at 100 mV/A for the -20A variant. Linearity ~0.4%. |+| 8 | VCC | power_in | Supply voltage input, nominally 5V. Powers the Hall front-end, chopper oscillator, temperature compensation, and output amplifier. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Cross chip |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++- `CC6900SO-20ASO-5A`+- `CC6900SO-20ASO-10A`+- `CC6900SO-20ASO-20A`+- `CC6900SO-20ASO-30A`++## CAD (KiCad official)++- Symbol: `CC6900SO-20A`+- 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/cc6900so-20a-datasheet.pdf) (3 pp, sha256 `e459878df789bbd5`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
