CI5930-50A from Tokmas, 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 | Current sampled positive terminal of the primary conductor; input current flowing from IP+ to IP- is defined as positive, and the input voltage at IP+ is limited to ±600 VPK relative to GND (pin 5). |
| 2 | IP+ | passive | Second current sampled positive terminal, internally tied to pin 1 as the primary conductor's positive end; input current is limited to ±50 A (DC/AC RMS) and 40 A continuous per the absolute maximum ratings. |
| 3 | IP- | passive | Current sampled negative terminal of the primary conductor; the input voltage at IP- is limited to ±600 VPK relative to GND (pin 5), and the isolation between pins 1-4 and 5-8 is 3500 VRMS. |
| 4 | IP- | passive | Second current sampled negative terminal, internally tied to pin 3 as the primary conductor's negative end; the primary conductor resistance is typically 0.9 mΩ at IP = 2 A. |
| 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 an internal benchmark of 2.470 V to 2.530 V at VCC = 5 V, whose source current is limited to 400 µA maximum and sink current to 3000 µA maximum. |
| 7 | OUT | output | Analog voltage output that sits at VCC/2 at zero current and moves with the input current; it is rated for a source current of 6 mA maximum and a sink current of 30 mA maximum, with a load of at most 1 nF capacitive and at least 1.5 kΩ resistive. |
| 8 | VCC | power_in | Single power supply input rated 4.5 V to 5.5 V (absolute maximum 7 V), drawing 20 mA typical and 25 mA maximum with OUT floated. |
