Texas Instruments introduced the industry’s most sensitive in-plane Hall-effect switch for position sensing, offering engineers a cost-effective, user-friendly alternative to magnetoresistive sensors.
TI’s TMAG5134 Hall-effect switch features an integrated magnetic concentrator, enabling it to detect magnetic fields as weak as 1mT in applications such as door and window sensors, personal electronics, home appliances, and more. This level of sensitivity allows for the use of smaller magnets, further reducing system-level costs. Additionally, the TMAG5134’s in-plane sensing capability enables it to detect magnetic fields parallel or horizontal to a printed circuit board, giving engineers greater design flexibility.
The TMAG5134 Hall-effect switch helps extend battery life in sensing applications by consuming just 0.6µA on average. Its integrated magnetic concentrator technology amplifies the sensor signal, eliminating the need to bias the device with as much current (more info).
