ACS3704x Leaded Magnetic Current Sensors

Allegro MicroSystems ACS3704x Leaded Magnetic Current Sensors are a fully integrated Hall-effect-based current sensor ICs that provide a galvanically isolated voltage output proportional to the sensed current. These sensors do not require an external sense resistor, simplifying system design and reducing component count. The ACS37041 and ACS37042 sensors feature an integrated conductor with low resistance for current measurement, reducing power losses and improving efficiency. The ACS37041 and ACS37042 employ a differential sensing technique with two Hall plates to effectively reject common-mode magnetic fields to ensure accurate and reliable current measurements.
