ACS37002 400kHz High Accuracy Current Sensor ICs

Allegro MicroSystems ACS37002 400kHz High Accuracy Current Sensor ICs is a fully integrated hall-effect current sensor with very high accuracy. The ACS37002 is ideal for control loops of the most demanding power conversion applications. Current flows through the ACS37002 Hall sensor IC via the internal conductor coupling the magnetic field generated. No physical connection between the current and the IC allows high-voltage isolation. The current is sensed differentially by two Hall plates that remove interfering external common-mode magnetic fields. The ACS37002 is factory-trimmed to provide high accuracy over the entire operating range without the requirement of further programming.
