TI unveils the industry’s most sensitive in-plane Hall-effect switch
Texas Instruments has 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 a 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.
Rohm has developed ultra-compact CMOS op amp delivering ultra-low circuit current
This IC is optimised to be applied as a measurement sensing amplifier in size-constrained applications such as handheld measurement instruments, wearable devices, and indoor motion detectors.
Rutronik adds Nordic Semiconductor’s power management IC for small battery products
Nordic Semiconductor’s nPM1304 expands Rutronik’s power management IC portfolio. By integrating essential functions required for embedded designs in a small package, enabling longer runtimes and efficient battery charging with fewer components, this PMIC simplifies system design. The nPM1304 PMIC builds on Nordic’s PMIC nPM1300 and is a highly integrated solution that offers extremely low power consumption and accurate fuel level measurement. Applications include smart rings or glasses, as well as body sensors, and other small battery applications that support charging currents up to 4 mA.
