ACS723LLCTR-10AB-T from Allegro MicroSystems, LLC, in a SOIC-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 | Terminal for the primary current being sensed, fused internally, with the current flowing from pins 1 and 2 to pins 3 and 4 giving a positive output slope. |
| 2 | IP+ | passive | Terminal for the primary current being sensed, fused internally, with the current flowing from pins 1 and 2 to pins 3 and 4 giving a positive output slope. |
| 3 | IP- | passive | Terminal for the primary current being sensed, fused internally, forming the return end of the primary conductor path with 0.65 mΩ typical resistance. |
| 4 | IP- | passive | Terminal for the primary current being sensed, fused internally, forming the return end of the primary conductor path with 0.65 mΩ typical resistance. |
| 5 | GND | power_in | Signal ground terminal, electrically isolated from the primary conductor pins 1 through 4. |
| 6 | BW_SEL | input | Terminal for selecting the 20 kHz or 80 kHz bandwidth, with the 80 kHz high-bandwidth mode selected when it is grounded. |
| 7 | VIOUT | output | Analog output signal proportional to the bidirectional primary current, with a zero-current level of 0.5 × VCC. |
| 8 | VCC | power_in | Device power supply terminal, operating from 4.5 to 5.5 V with 6 V as the absolute maximum supply voltage. |
