TMAG5123 High-Voltage In-Plane High-Precision Switch

Texas Instruments' chopper-stabilized Hall sensor features a digital omnipolar switch output for magnetic sensing applications

Image of Texas Instruments' TMAG5123 High-Voltage High-Precision SwitchTexas Instruments' TMAG5123 is a chopper-stabilized omnipolar, active-low, in-plane, Hall-effect switch sensor. The TMAG5123 eases the mechanical placement of the sensor by measuring magnetic fields that are 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 requirements 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 in absolute terms. The TMAG5123 incorporates a wide 2.5 V to 38 V operating voltage range and reverse polarity protection of up to -20 V, enabling robust operation for industrial applications.
