CC6937S8-5FB020 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 pin, paired with pin 2 on the IP+ side; current flowing from IP+ to IP- is positive, and the internal primary conductor resistance is typically 0.5 mΩ. |
| 2 | IP+ | passive | Primary current input pin, paired with pin 1 on the IP+ side; current flowing from IP+ to IP- is positive, and the sensor should be connected in series with the measured circuit without shunt resistors across IP+ and IP-. |
| 3 | IP- | passive | Primary current return pin, paired with pin 4 on the IP- side; current flowing into IP- from IP+ is treated as the positive direction, and reverse current is negative. |
| 4 | IP- | passive | Primary current return pin, paired with pin 3 on the IP- side; the primary side is isolated from the secondary pins 5-8 with 3750 VRMS withstand voltage. |
| 5 | GND | power_in | Ground reference for the sensor's secondary circuit and the VOUT and VREF outputs. |
| 6 | VREF | power_in | Reference voltage pin that works as an output (2.500 V nominal in the 5 V series, recommended load about 2 mA) or as an input accepting 0 to 4 V, and it sets the VOUT quiescent level. |
| 7 | VOUT | output | Analog output whose quiescent level is VREF (2.5 V at 5 V supply) and which moves by IP × 100 mV/A for the CC6937S8-5FB020, with a 1.5 kΩ minimum load and 1 to 2.2 nF filter capacitor recommended. |
| 8 | VCC | power_in | Supply voltage pin; the 5 V series runs from 4.5 to 5.5 V and the absolute maximum rating is 6.5 V. |
