The TMAG5233 is an in-plane Hall-effect switch designed to replace TMR, AMR and Reed switches used in applications where cost is a priority.

The TMAG5233 has an omnipolar magnetic response and enables the device to react to both north and south magnetic poles. When the applied magnetic flux density through the sensor axis of sensitivity exceeds the operate point threshold (BOP), the device outputs a low voltage. 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 TMAG5233 is internally duty-cycled. The device has a push-pull (CMOS) output which eliminates the need for an external pullup resistor, and is available in an industry-standard SOT-23 package.
