Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Positive sampled-current terminal of the primary conductor; input current is positive when it flows from IP+ (pins 1-2) to IP- (pins 3-4), and external resistors should not be placed between IP+ and IP-. |
| 2 | IP+ | passive | Second positive sampled-current terminal of the primary conductor, paired with pin 1; input current is positive when it flows from IP+ to IP-. |
| 3 | IP- | passive | Negative sampled-current terminal of the primary conductor; current flowing from IP+ into IP- is the positive direction. |
| 4 | IP- | passive | Second negative sampled-current terminal of the primary conductor, paired with pin 3; current flowing from IP+ into IP- is the positive direction. |
| 5 | GND | power_in | Ground reference for the device; VOUT(Q), VREF and the filter capacitors COUT and CREF are referenced to GND. |
| 6 | VREF | power_in | Reference voltage pin that works either as a built-in output (about 2.5 V on the 5 V series, factory-programmed to within 5 mV, recommended load current up to 2 mA) or as an external input from 0 V to 4 V, with a 1 nF to 2.2 nF filter capacitor to GND. |
| 7 | VOUT | output | Analog output voltage that is referenced to VREF at zero current and swings with the input current; it needs a 1 nF to 2.2 nF filter capacitor to GND and a load of at least 1.5 kΩ to GND. |
| 8 | VCC | power_in | Supply voltage pin; the CC6937S8-5FB005 is a 5 V series part with VCC of 4.5 V to 5.5 V (5 V nominal) and an absolute maximum of 6.5 V. |
