Low-tolerance high-sensitivity in-plane Hall-effect switch

The TMAG5133 is an in-plane Hall-effect switch designed to replace TMR, AMR and Reed switches. The device is optimized to enable small form factors across industrial and consumer applications with ultra-low power consumption, wide supply and temperature ranges.

The TMAG5133 has two unipolar outputs or a single omnipolar which enable the device to react to external magnetic fields. When the applied magnetic flux density through the sensor axis of sensitivity exceeds the operate point threshold (BOP), the device outputs a low voltage on the respective pin. The output stays low until the magnetic flux density decreases to less than the release point threshold (BRP), after which the device outputs a high voltage.

To minimize power consumption, the TMAG5133 is internally duty-cycled. The device has a push-pull output which eliminates the need for an external pullup resistor, and is available in an industry standard X1LGA package.
