IC Packs Fluxgate Sensor, Signal Conditioning, And Compensation Coil Driver
Texas Instruments Inc.

The DRV421 emerges as the industry's first magnetic sensing IC that integrates a fluxgate sensor and compensation coil driver along with all necessary signal conditioning circuitry. Features and benefits include:
• Simplifies system design: An integrated fluxgate sensor reduces design complexity and design effort, and helps achieve smaller footprint.
• Sensor integration enables best-in-class accuracy and linearity: ◦Allows precise control over motors and automation equipment with an overall sensor accuracy of less than 0.1 percent.
• Reduces coupling between the compensation coil and the fluxgate sensor, as well as emissions from fluxgate excitation, to provide high linearity
• High dynamic range: Built-in closed-loop magnetic core degaussing procedure and offset calibration increase dynamic range up to six decades while supporting higher system-level accuracy, compared to traditional solutions.
• Allows 3.3-V operation: As the first fluxgate sensor solution on the market supporting 3.3-V operation, the DRV421 simplifies the interface to integrated ADCs on low-power microcontrollers.

The DRV421 comes in a 4 mm x 4 mm QFN package. Production quantities will be available in 3Q2015 for a price $2.50 each/1,000. TI is demonstrating this technology at booth 217 at Sensors Expo on June 9-11 in Long Beach, Calif. For more information, visit http://www.ti.com/drv421-pr and http://www.sensorsexpo.com
