Cross chip · Current Sensors · SOP-8
CC6905S8-3FU030 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 | Current sampled positive terminal of the internal copper conductor; pins 1-4 are isolated from pins 5-8 at 100 VRMS (50/60 Hz, 1 min). |
| 2 | IP+ | passive | Second current sampled positive terminal of the internal copper conductor, bonded to pin 1 and isolated from pins 5-8 at 100 VRMS (50/60 Hz, 1 min). |
| 3 | IP- | passive | Current sampled negative terminal of the internal copper conductor, bonded to pin 4 and isolated from pins 5-8 at 100 VRMS (50/60 Hz, 1 min). |
| 4 | IP- | passive | Second current sampled negative terminal of the internal copper conductor, bonded to pin 3 and isolated from pins 5-8 at 100 VRMS (50/60 Hz, 1 min). |
| 5 | GND | power_in | Ground reference for the sensor's secondary (signal and supply) circuit, isolated from the IP+/IP- current path on pins 1-4. |
| 6 | VREF | power_in | Built-in reference voltage output; the datasheet states VOE is programmable to < 5 mV and that VOUT quiescent voltage follows an external VREF input when one is used. |
| 7 | VOUT | output | Single-ended analog output voltage carrying the measured current signal; absolute maximum is VCC + 0.3 V and source current is limited to 25 mA. |
| 8 | VCC | power_in | Supply voltage input; absolute maximum rating is 6.5 V. |
