Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IP+ | passive | Positive terminal of the internal primary current-sense conductor; tie to pin 2 externally. Fused internally, 0.65 mΩ path resistance, 65 A ICMAX at 25 °C. |+| 2 | IP+ | passive | Positive terminal of the internal primary current-sense conductor; tie to pin 1 externally. Fused internally, 0.65 mΩ path resistance. |+| 3 | IP- | passive | Negative terminal of the internal primary current-sense conductor; tie to pin 4 externally. Fused internally; galvanically isolated (2.4 kVrms dielectric strength) from the signal pins 5-8. |+| 4 | IP- | passive | Negative terminal of the internal primary current-sense conductor; tie to pin 3 externally. Fused internally; galvanically isolated from signal-side pins. |+| 5 | GND | power_in | Signal ground reference for VCC, VIOUT, and BW_SEL. Isolated from the primary conductor (IP+/IP-). |+| 6 | BW_SEL | input | Bandwidth-select input. Leave floating (or tie to VCC) for 20 kHz low-noise mode; tie to GND for 80 kHz high-bandwidth mode. |+| 7 | VIOUT | output | Analog output voltage, ratiometric to VCC. Bidirectional signal centered at VCC/2 with 400 mV/A sensitivity for the -05AB variant (±5 A full-scale range). Recommend a CL bypass capacitor from VIOUT to GND. |+| 8 | VCC | power_in | Device supply voltage input, 4.5 V to 5.5 V (nominal 5 V). Absolute maximum 6 V. Decouple to GND with a 0.1 µF ceramic capacitor (CBYPASS). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Allegro MicroSystems LLC |+| Package | SOIC-8 |+| Category | Magnetic Sensors |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `ACS723LLCTR-05AB-T`+- `ACS723LLCTR-10AU-T`+- `ACS723LLCTR-10AB-T`+- `ACS723LLCTR-20AU-T`+- `ACS723LLCTR-20AB-T`+- `ACS723LLCTR-40AU-T`+- `ACS723LLCTR-40AB-T`+- `ACS723LLCTR-50AB-T`++## CAD (KiCad official)++- Symbol: `ACS723LLCTR-05AB-T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Allegro MicroSystems LLC datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588941876573442048) (24 pp, sha256 `29b651eb6a6c9277`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
