Allegro MicroSystems, LLC · Current Sensors · SOIC-8
ACS714ELCTR-05B-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 current being sampled, fused internally and tied to pin 2; primary path has 1.2 mΩ typical resistance and is isolated from signal pins 5-8 (2.1 kVRMS minimum). |
| 2 | IP+ | passive | Terminal for current being sampled, fused internally and tied to pin 1; primary path has 1.2 mΩ typical resistance and is isolated from signal pins 5-8 (2.1 kVRMS minimum). |
| 3 | IP- | passive | Terminal for current being sampled, fused internally and tied to pin 4; current flowing from pins 1 and 2 to pins 3 and 4 gives a positive output slope. |
| 4 | IP- | passive | Terminal for current being sampled, fused internally and tied to pin 3; current flowing from pins 1 and 2 to pins 3 and 4 gives a positive output slope. |
| 5 | GND | power_in | Signal ground terminal. |
| 6 | FILTER | passive | Terminal for external capacitor CF to ground that sets the bandwidth (1 nF in the typical application); internal filter resistance is 1.7 kΩ. |
| 7 | VIOUT | output | Analog output signal, VCC×0.5 at zero current, requiring a load of at least 4.7 kΩ and at most 10 nF to GND. |
| 8 | VCC | power_in | Device power supply terminal, 4.5 V to 5.5 V (5.0 V typical), with a 0.1 µF bypass capacitor; absolute maximum 8 V. |
