ACS37010 Current Sensor

Allegro's ACS37010 is a high accuracy, 450 kHz fully integrated Hall effect current sensor in a fused-lead SOIC-6 package. Current flows through the internal conductor coupling the magnetic field generated to the Hall sensor IC. As a result of no physical connection between the current and the IC, high isolation is achieved. The current is sensed differentially by two Hall plates that subtract out interfering external common-mode magnetic fields. The sensor is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming.

The ACS37010 is offered in the LZ fused-lead SOIC-6 package, providing 420 V_RMS reinforced isolation in a compact and more cost-effective package versus the comparable SOICW-16 package. The sensor features a voltage reference output pin for use in noisy supply environments.

The SOIC-6 package has lower conductor resistance versus standard SOIC-8 packages and supports higher isolation up to 840 V_RMS basic isolation or 420 V_RMS reinforced isolation.
