Cross chip · Current Sensors · SOP-8

CC6920BSO-40A 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 primary conductor; pins 1 and 2 are internally common and the current flowing from IP+ to IP- is defined as positive, with the primary rated at 40 A continuous and 100 A peak for 3 s (absolute maximum).
2 IP+ passive Current sampled positive terminal of the internal copper primary conductor, internally common with pin 1; the isolation between pins 1-4 and 5-8 is 3500 VRMS.
3 IP- passive Current sampled negative terminal of the internal copper primary conductor, internally common with pin 4; current entering IP+ and leaving IP- is positive.
4 IP- passive Current sampled negative terminal of the internal copper primary conductor, internally common with pin 3; input voltage on the IP pins is specified up to ±600 VPK relative to GND (pin 5).
5 GND power_in Ground reference for the device; the primary input voltages on IP+ and IP- are referenced to this pin.
6 VZCR output Zero current reference signal output, internal benchmark 1.65 V typical at VCC = 3.3 V, with reference output source current limited to 400 µA max and sink current limited to 3000 µA max.
7 OUT output Analog voltage output with VOUT(Q) = VCC/2 at zero current; absolute maximum output source current is 6 mA and sink current 30 mA, with a recommended resistive load of at least 1.5 kΩ and capacitive load of at most 1 nF.
8 VCC power_in Single power supply input, recommended 3.0 V to 3.6 V (3.3 V typical), with an absolute maximum rating of 7 V.
