CC6904SO-20A
Cross chip · Current Sensors · SOP-8
CC6904SO-20A 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 | Primary sampling-current positive terminal (one of two pins on the current conductor), rated for the ±20 A measuring range of the CC6904SO-20A, with 2000 V isolation from the signal pins. |
| 2 | IP+ | passive | Primary sampling-current positive terminal (second pin of the same conductor, connected in parallel with pin 1), rated for the ±20 A measuring range of the CC6904SO-20A. |
| 3 | IP- | passive | Primary sampling-current negative terminal (one of two pins on the current conductor), rated for the ±20 A measuring range of the CC6904SO-20A. |
| 4 | IP- | passive | Primary sampling-current negative terminal (second pin of the same conductor, connected in parallel with pin 3), rated for the ±20 A measuring range of the CC6904SO-20A. |
| 5 | GND | power_in | Ground reference for the device; the absolute maximum output voltage is limited to -0.3 V to VCC+0.3 V relative to this pin. |
| 6 | NC | unconnected | Not connected; the datasheet states this pin must be left floating. |
| 7 | OUT | output | Single-ended analog signal output with a static point of VCC/2 (1.65 V at 3.3 V), limited to a source current of 400 µA and a sink current of 30 mA, and a load of at least 20 kΩ and at most 1 nF. |
| 8 | VCC | power_in | Supply voltage: recommended 3.0 V to 3.6 V, absolute maximum 7 V. |
