Innovative Magnetic Sensing Integrated IC

Texas Instruments recently unveiled the DRV421 magnetic sensing IC with a fully integrated fluxgate sensor and compensation coil driver. It includes all the required signal conditioning circuitry.DRV421_TI

Compared to traditional Hall effect sensors, the DRV421 provides high sensor accuracy and linearity, high dynamic range, and simpler system design. With it, you can easily design magnetic closed-loop current sensors for a variety of applications (e.g., motor control, renewable energy, battery chargers and power monitoring).

The $49 DRV421 evaluation module (DRV421EVM) makes it easy to evaluate the new current sensing IC’s features and performance. The DRV421 comes in a 4 mm- × 4 mm QFN package. Pre-production samples are available now. Production quantities will be available in Q3 2015 for 2.50 in 1,000-unit quantities.
