The TMAG5123-Q1 is a chopper-stabilized omnipolar, active-low, in-plane, Hall-effect switch sensor. The TMAG5123-Q1 eases mechanical placement of the sensor by measuring magnetic fields parallel to the surface of the printed circuit board (PCB) in a surface mount SOT-23 package.

Different sensitivity levels are available to match the specific requirement of the application. When the applied magnetic flux density value exceeds the operating point (BOP) threshold in absolute magnetic field values, the open-drain output produces a low-state voltage. The output remains low until the applied field decreases to less than the release point (BRP) threshold also in absolute terms.

The TMAG5123-Q1 incorporates a wide 2.7-V to 38-V operating voltage range and reverse polarity protection of up to -20-V, enabling robust operation for industrial and automotive applications.
