DRV421 Datasheet (Texas Instruments) - Integrated Magnetic Fluxgate Sensor

DRV421, Integrated Magnetic Fluxgate Sensor

The DRV421 is designed for magnetic closed-loop current sensing solutions, enabling isolated, precise dc- and ac-current measurements.

This device provides both, a proprietary integrated fluxgate sensor, and the required analog signal conditioning, thus minimizing component count and cost.
