Description for the TMAG5123-Q1

The TMAG5123-Q1 is a chopper-stabilized omnipolar, active-low Hall-effect switch sensor. The TMAG5123-Q1 integrates an in-plane sensor enabling the sensing of horizontal fields. Available in the SOT-23 package, the TMAG5123-Q1 allows measuring magnetic fields that are parallel to the surface of the printed circuit board (PCB) to ease mechanical placement.

Different sensitivity levels are available to match the specific requirement of the application. When the applied magnetic flux density value exceeds the 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 BRP threshold also in absolute terms.

The TMAG5123-Q12.7-V to 38-V operating voltage range and reverse polarity protection of up to –20-V for the device is designed for a wide range of industrial and automotive applications.
