Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IP+ | passive | Current sampled positive terminal of the internal copper primary conductor; pins 1 and 2 are internally common and the current flowing from IP+ to IP- is defined as positive, with the primary rated at 40 A continuous and 100 A peak for 3 s (absolute maximum). |
| 2 | IP+ | passive | Current sampled positive terminal of the internal copper primary conductor, internally common with pin 1; the isolation between pins 1-4 and 5-8 is 3500 VRMS. |
| 3 | IP- | passive | Current sampled negative terminal of the internal copper primary conductor, internally common with pin 4; current entering IP+ and leaving IP- is positive. |
| 4 | IP- | passive | Current sampled negative terminal of the internal copper primary conductor, internally common with pin 3; input voltage on the IP pins is specified up to ±600 VPK relative to GND (pin 5). |
| 5 | GND | power_in | Ground reference for the device; the primary input voltages on IP+ and IP- are referenced to this pin. |
| 6 | VZCR | output | Zero current reference signal output, internal benchmark 1.65 V typical at VCC = 3.3 V, with reference output source current limited to 400 µA max and sink current limited to 3000 µA max. |
| 7 | OUT | output | Analog voltage output with VOUT(Q) = VCC/2 at zero current; absolute maximum output source current is 6 mA and sink current 30 mA, with a recommended resistive load of at least 1.5 kΩ and capacitive load of at most 1 nF. |
| 8 | VCC | power_in | Single power supply input, recommended 3.0 V to 3.6 V (3.3 V typical), with an absolute maximum rating of 7 V. |
