7.1 Overview

The TMAG5233 is an alternative to expensive TMR, AMR and Reed switches, enabling magnetic position sensing for cost-optimized designs. The TMAG5233 is a Hall-effect sensor with a single digital output that indicates when the magnetic flux density thresholds (BOP and BRP) have been crossed. The output features a push-pull (CMOS) architecture that allows the device to drive the output high or pull the output low, eliminating the need for an external pullup resistor.

As an omnipolar switch, the TMAG5233 OUT pin responds to both positive and negative magnetic flux density along the axis of sensitivity on the sensor. As seen in Figure 7-2, a south pole near pin 1 of the DBV package induces a positive magnetic flux density, while a north pole near pin 1 of the DBV package induces a negative magnetic flux density. The output type is active low, meaning the device pulls the output pin low when the magnetic flux density exceeds BOP and drives the output high when the magnetic flux density falls below BRP .

The TMAG5233 integrates a Hall-effect element, analog signal conditioning, and a low-frequency oscillator. The TMAG5233 operates as a duty-cycled device, periodically measuring the magnetic flux density, updating the output, and entering a low-power sleep state between measurements to conserve power.
