ACS709 Current Sensor Carrier -75A to +75A

Clearance notice: These older current sensors are on clearance at a discounted price and will be discontinued once remaining component stock is depleted.

This board is a simple carrier of Allegro’s bidirectional ±75A ACS709 Hall effect-based linear current sensor with overcurrent fault output, which offers a low-resistance (~1.1 mΩ) current path and electrical isolation. The sensor has optimized accuracy for currents from -37.5 A to 37.5 A, and the analog voltage output is linear for current magnitudes up to 75 A. The ratiometric output voltage is centered at VCC/2 and has a typical error of ±2%. It operates from 3 V to 5.5 V, so it can interface directly to both 3.3 V and 5 V systems.
