CC6920SO-30A 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; current flowing from IP+ to IP- is defined as positive, and the input voltage on IP+/IP- is limited to ±600 VPK relative to pin 5 (GND) under recommended operating conditions. |
| 2 | IP+ | passive | Primary current input (second IP+ pin, bonded in parallel with pin 1); current flowing from IP+ to IP- is defined as positive, and the input voltage is limited to ±600 VPK relative to pin 5 (GND). |
| 3 | IP- | passive | Primary current return; the device is meant to be connected in series in the circuit, and external resistors should not be shunted between IP+ and IP- except for very special reasons. |
| 4 | IP- | passive | Primary current return (second IP- pin, bonded in parallel with pin 3); the device is meant to be connected in series in the circuit, and external shunt resistors between IP+ and IP- are not recommended. |
| 5 | GND | power_in | Ground reference; the IP+ and IP- input voltages are specified relative to this pin. |
| 6 | VZCR | output | Zero current reference signal output with source current limited to 400 µA and sink current limited to 3000 µA; the datasheet advises keeping the output current below 0.4 mA and reserving 0.3 mA in design. |
| 7 | OUT | output | Analog voltage output that equals VCC/2 at zero current and changes by 67 mV/A for the 30A variant; the datasheet recommends a resistive load of at least 1.5 kΩ and a capacitive load of at most 1 nF. |
| 8 | VCC | power_in | Single power supply input, 4.5 V minimum to 5.5 V maximum (5 V typical), with supply current of 20 mA typical and 25 mA maximum with OUT floated. |
