ACS724LMATR-50AB-T from Allegro MicroSystems, LLC, in a SOIC-16-300mil. 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 current being sensed, fused internally; current flows from pins 1-4 to pins 5-8 with 0.85 mΩ typical primary conductor resistance. |
| 2 | IP+ | passive | Terminal for current being sensed, fused internally; current flows from pins 1-4 to pins 5-8 with 0.85 mΩ typical primary conductor resistance. |
| 3 | IP+ | passive | Terminal for current being sensed, fused internally; current flows from pins 1-4 to pins 5-8 with 0.85 mΩ typical primary conductor resistance. |
| 4 | IP+ | passive | Terminal for current being sensed, fused internally; current flows from pins 1-4 to pins 5-8 with 0.85 mΩ typical primary conductor resistance. |
| 5 | IP- | passive | Terminal for current being sensed, fused internally; current exits here after flowing through the primary conductor from pins 1-4. |
| 6 | IP- | passive | Terminal for current being sensed, fused internally; current exits here after flowing through the primary conductor from pins 1-4. |
| 7 | IP- | passive | Terminal for current being sensed, fused internally; current exits here after flowing through the primary conductor from pins 1-4. |
| 8 | IP- | passive | Terminal for current being sensed, fused internally; current exits here after flowing through the primary conductor from pins 1-4. |
| 9 | NC | unconnected | No internal connection; recommended to be left unconnected to maintain high creepage. |
| 10 | VCC | power_in | Device power supply terminal, 4.5 to 5.5 V operation (6 V absolute maximum), with a 0.1 µF bypass capacitor shown to ground. |
| 11 | NC | unconnected | No internal connection; recommended to connect to GND for the best ESD performance. |
| 12 | VIOUT | output | Analog output signal proportional to the sensed current, with load of at least 4.7 kΩ and up to 10 nF capacitance to GND. |
| 13 | FILTER | passive | Terminal for external capacitor that sets bandwidth, forming an RC filter with the 1.7 kΩ typical internal filter resistance. |
| 14 | NC | unconnected | No internal connection; recommended to connect to GND for the best ESD performance. |
| 15 | GND | power_in | Signal ground terminal. |
| 16 | NC | unconnected | No internal connection; recommended to be left unconnected to maintain high creepage. |
