# CC6902SO-5B

**Cross chip** · Current Sensors · SOP-8

CC6902SO-5B from Cross chip, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Sampled-current positive terminal of the primary conductor, as defined in the datasheet pin table. |
| 2 | IP+ | passive | Sampled-current positive terminal of the primary conductor; pin 2 is internally tied to the same sense path as pin 1 (second IP+ pin). |
| 3 | IP- | passive | Sampled-current negative terminal of the primary conductor, as defined in the datasheet pin table. |
| 4 | IP- | passive | Sampled-current negative terminal of the primary conductor; pin 4 is the second IP- pin on the same sense path as pin 3. |
| 5 | GND | power_in | Ground reference for the sensor, as defined in the datasheet pin table. |
| 6 | NC | unconnected | Not connected; the datasheet states this pin must be left floating. |
| 7 | OUT | output | Single-ended analog signal output; the datasheet states OUT swings between 0.5 V and 4.5 V linearly with magnetic field at a 5 V supply, with a static (zero-field) output of 50% VCC. |
| 8 | VCC | power_in | Supply voltage input; the datasheet's characterization uses 5 V supply and the output is 50% VCC at zero field. |
