In-plane (X-axis) Hall-effect switch

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.
