JSM6900SO-5A from JSMSEMI, 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 | Positive terminal of the primary current input path, tied to pin 2 and carrying the measured current. |
| 2 | IP+ | passive | Positive terminal of the primary current input path, tied to pin 1 and carrying the measured current. |
| 3 | IP- | passive | Negative terminal of the primary current input path, tied to pin 4 and carrying the measured current. |
| 4 | IP- | passive | Negative terminal of the primary current input path, tied to pin 3 and carrying the measured current. |
| 5 | GND | power_in | Ground, also used as a programming pin. |
| 6 | TEST | unconnected | Factory test pin, to be left floating. |
| 7 | OUT | output | Analog signal output (quiescent point 2.5 V, source current max 80 mA, sink current max 40 mA), also used as a programming pin. |
| 8 | VCC | power_in | Power supply input, 4.5 V to 5.5 V operating (6 V absolute maximum), also used as a programming pin. |
