TI Introduces High-Sensitivity TMAG5134 In-Plane Hall-Effect Switch for Cost-Effective Position Sensing

Texas Instruments  has launched the TMAG5134, an in-plane Hall-effect switch with an integrated magnetic concentrator, capable of detecting magnetic fields as low as 1mT. The sensor targets position-sensing applications such as door and window sensors, personal electronics, and home appliances, offering a cost-effective alternative to magnetoresistive sensors like TMR, AMR, and GMR, as well as reed switches.

The TMAG5134’s high sensitivity enables the use of smaller magnets, reducing system costs. Its in-plane sensing detects magnetic fields parallel or horizontal to a printed circuit board, providing design flexibility. Unlike magnetoresistive sensors, which require specialized materials and fabrication, the TMAG5134 leverages Hall-effect technology to simplify manufacturing and lower costs, addressing the limitations of traditional Hall-effect sensors’ sensitivity.

Jason Cole, Vice President and General Manager of Sensing Products at TI, stated that the TMAG5134 enables engineers to achieve high sensitivity in compact, low-power designs, supporting applications in smart home systems and personal electronics. The sensor consumes an average of 0.6µA, extending battery life, and its integrated magnetic conce...
