CC6937S8-5FB030 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 | Sampled-current positive terminal of the internal primary conductor, rated for measuring -30 A to +30 A for CC6937S8-5FB030, with current flowing IP+ to IP- defined as positive and the device placed in series with no parallel resistor across IP+ and IP-. |
| 2 | IP+ | passive | Sampled-current positive terminal (second IP+ pin, bonded in parallel with pin 1), rated for -30 A to +30 A for CC6937S8-5FB030 with current flowing IP+ to IP- defined as positive. |
| 3 | IP- | passive | Sampled-current negative terminal of the internal primary conductor, where current leaving this pin in the series loop is the negative direction, and no external resistor should be placed in parallel between IP+ and IP-. |
| 4 | IP- | passive | Sampled-current negative terminal (second IP- pin, bonded in parallel with pin 3), used with the same series connection and polarity convention as IP+ and IP-. |
| 5 | GND | power_in | Ground reference pin for the sensor; the datasheet gives no separate electrical limit for this pin and it is the reference for VOUT, VREF and the short-circuit current ratings. |
| 6 | VREF | power_in | Reference voltage pin that works as an output (2.45 V to 2.55 V for the 5 V series, typical source 2.8 mA and sink 6 mA, recommended load ≤2 mA) or as an input (0 V to 4 V), and sets the zero-current output VOUT(Q). |
| 7 | VOUT | output | Analog output voltage, VOUT = VREF + IP × 66.67 mV/A for this part, guaranteed linear from 0.5 V to 4.5 V with a required filter capacitor of 1 nF to 2.2 nF to GND and load resistance of at least 1.5 kΩ, with short-circuit current of 30 mA to GND and 23 mA to VCC. |
| 8 | VCC | power_in | Supply voltage pin with a 6.5 V absolute maximum rating, and the 5 V series operates from 4.5 V to 5.5 V (nominal 5 V) with an undervoltage release threshold of 2.7 V. |
