TMAG5124 Hall-Effect Switch Sensor

Texas Instruments TMAG5124 Hall-Effect Switch Sensor is a high-precision Hall effect sensor with a 2-wire interface designed for industrial designs. The TMAG5124 integrates a current source that switches between two levels depending on the value of the magnetic field applied to the part. While the high value is fixed, the low value can be selected from two ranges. This type of interface enables robust communication between sensor and controller, allows long-distance transmissions, helps detect disconnections, and limits the number of wires to two.
