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 sense positive terminal. Internally tied to pin 2; both pins carry the sensed current into the integrated primary conductor (Rp ≈ 1.5 mΩ). Galvanically isolated (100 VAC) from the signal-side pins. |+| 2 | IP+ | passive | Primary current sense positive terminal (paralleled with pin 1). Together pins 1-2 form the positive side of the integrated primary conductor. |+| 3 | IP- | passive | Primary current sense negative terminal. Internally tied to pin 4; both pins form the return side of the integrated primary conductor. Galvanically isolated (100 VAC) from the signal-side pins. |+| 4 | IP- | passive | Primary current sense negative terminal (paralleled with pin 3). Together pins 3-4 form the negative side of the integrated primary conductor. |+| 5 | GND | power_in | Signal ground. Ground reference for the internal analog circuitry and OUT pin. |+| 6 | NC | unconnected | No connect. Must be left floating (需悬空) per the pin description table. |+| 7 | OUT | output | Analog signal output. Ratiometric to VCC with a quiescent level of VCC/2 (typ 1.65 V at 3.3 V VCC). For the -20A variant, VOUT = VCC/2 + 0.066 × IP(A). Source capability 400 µA, sink capability 30 mA; guaranteed linear range 0.33-2.97 V. |+| 8 | VCC | power_in | Supply voltage input. Recommended operating range 3.0-3.6 V (absolute max 7 V). Typical ICC ≈ 5 mA. Bypass 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++- `CC6903SO-20ACC6903SO-10A`+- `CC6903SO-20A`+- `CC6903SO-20ACC6903SO-30A`++## CAD (KiCad official)++- Symbol: `CC6903SO-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/cc6903so-20a-datasheet.pdf) (12 pp, sha256 `4caefefced8b515b`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
