ACS724LLCTR-05AB-T-JSM 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 | Current input positive terminal (primary conductor), shorted with pin 2. |
| 2 | IP+ | passive | Current input positive terminal (primary conductor), shorted with pin 1. |
| 3 | IP- | passive | Current input negative terminal (primary conductor), shorted with pin 4. |
| 4 | IP- | passive | Current input negative terminal (primary conductor), shorted with pin 3. |
| 5 | GND | power_in | Ground pin, also used as a programming pin. |
| 6 | TEST | unconnected | Factory test pin; leave floating. |
| 7 | OUT | output | Analog signal output proportional to the sensed current (also a programming pin); absolute maximum VCC-0.5 V, source 80 mA, sink 40 mA. |
| 8 | VCC | power_in | Power supply pin, 4.5 V to 5.5 V operating (6 V absolute maximum), also used as a programming pin. |
