ADVANCE INFORMATION
The TMAG5233 is a low cost, in-plane Hall-effect switch designed to replace TMR, AMR and Reed switches used in magnetic position sensing applications.
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. The D1E device version has a BOP threshold of 3mT and BRP threshold of 2.2mT.
To minimize power consumption, the TMAG5233 is internally duty-cycled at 40Hz (D1E device version) operating with an average current consumption of 2.7µA. 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.
