Integrated Fluxgate Sensor, Signal Conditioning and Com-pensation Coil Driver IC

Integrated Fluxgate Sensor, Signal Conditioning and Com-pensation Coil Driver IC

Texas Instruments introduced the industry’s first magnetic sensing integrated circuit (IC) with a fully integrated fluxgate sensor and compensation coil driver, along with all the required signal conditioning circuitry. Complete integration enables the DRV421 to provide best-in-class sensor accuracy and linearity, high dynamic range, and simpler system design compared to traditional closed-loop sensors. With the DRV421, system designers will be able to more easily develop magnetic closed-loop current sensors for applications such as motor control, renewable energy, battery chargers and power monitoring. The DRV421 evaluation module (DRV421EVM) enables designers to quickly and easily evaluate the new current sensing IC’s features and performance. It is available for purchase for US$49 via the TI store and authorized distributors.

In addition, SUMIDA CORPORATION has introduced the SC2912, a magnetic module that system designers can place on top of the DRV421 as a printed circuit board (PCB) component. This allows engineers to design universal platform solutions targeting a wide range of current levels while choosing the appropriate magnetic module for their specific use case.
