ACS723LLCTR-05AB-T from Allegro MicroSystems LLC, in a SOIC-8. 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). |
