CC6920BSO-25A

Cross chip · Current Sensors · SOP-8

CC6920BSO-25A 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 current input (positive terminal, paired with pin 2); current flowing from IP+ to IP- is defined as positive, and the primary is isolated from the signal pins with 3500 VRMS withstand voltage.
2 IP+ passive Primary current input (positive terminal, paired with pin 1); current flowing from IP+ to IP- is defined as positive, and the primary is isolated from the signal pins with 3500 VRMS withstand voltage.
3 IP- passive Primary current input (negative terminal, paired with pin 4); the input current is measured as flowing from IP+ to IP-, and the primary is isolated from the signal pins with 3500 VRMS withstand voltage.
4 IP- passive Primary current input (negative terminal, paired with pin 3); the input current is measured as flowing from IP+ to IP-, and the primary is isolated from the signal pins with 3500 VRMS withstand voltage.
5 GND power_in Ground reference; the recommended input voltage range on IP+/IP- is specified relative to this pin, at -600 to 600 VPK.
6 VZCR output Zero Current Reference Signal Output, typically 1.65 V at VCC = 3.3 V, with reference output source current limited to 400 µA max and sink current to 3000 µA max.
7 OUT output Analog voltage output, VOUT = VCC/2 + sensitivity × IP, accurate over 0.33 to 2.97 V; absolute maximum output sink current is 30 mA and source current is 6 mA.
8 VCC power_in Single power supply input, 3.0 V to 3.6 V recommended (3.3 V typical), with an absolute maximum rating of 7 V.
