ACS724LLCTR-20AU-T from Allegro MicroSystems LLC, in a SOP-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 | Primary current path positive terminal; current flows through this terminal, internally fused, with 1.2 mΩ typical resistance. |
| 2 | IP+ | passive | Primary current path positive terminal; current flows through this terminal, internally fused, with 1.2 mΩ typical resistance. |
| 3 | IP- | passive | Primary current path negative terminal; current flows through this terminal, internally fused, with 1.2 mΩ typical resistance. |
| 4 | IP- | passive | Primary current path negative terminal; current flows through this terminal, internally fused, with 1.2 mΩ typical resistance. |
| 5 | GND | power_in | Signal ground terminal; reference potential for the analog output signal VIOUT and sensor IC secondary side. |
| 6 | FILTER | passive | External capacitor connection for bandwidth filtering; forms RC circuit with internal 1.8 kΩ resistance to optimize noise and resolution. |
| 7 | VIOUT | output | Analog output signal proportional to primary sensed current in 0-20 A range; unidirectional output with quiescent voltage of 0.1 × VCC nominal (approximately 0.5 V at 5 V supply). |
| 8 | VCC | power_in | Device power supply terminal; operates at 4.5-5.5 V nominal with typical supply current of 10-14 mA. |
