The TMAG5134 in-plane Corridor-effect swap from TI provides an economical different to magnetoresistive (MR) sensors for place sensing. An built-in magnetic concentrator permits detection of magnetic fields as weak as 1 mT in door and window sensors, residence home equipment, and private electronics. Its in-plane sensing provides design flexibility by detecting magnetic fields parallel or horizontal to the PC board.
Designers sometimes don’t take into account Corridor-effect switches as viable replacements for reed switches or tunnel, anisotropic, and big MR sensors due to their restricted sensitivity. The TMAG5134 overcomes this limitation, delivering greater sensitivity than standard Corridor-effect sensors with out the added value and complexity of MR units.
Working from a 1.65-V to five.5-V provide, the TMAG5134 consumes simply 0.6 µA on common. Its magnetic concentrator amplifies the sensor sign, eliminating the necessity for added bias present. The gadget provides versatile magnetic pole detection (omnipolar or dual-unipolar) and is out there with push-pull or open-drain outputs, in each active-low and active-high configurations. Magnetic working factors vary from 1 mT to 2 mT for versatile position-sensing purposes.
Manufactured in TI’s superior 300-mm fabs, the TMAG5134 is out there in manufacturing portions on TI.com.
