Description

The TMAG5124 device is a high-precision Hall effect sensor that offers a 2-wire output interface designed for industrial designs.

The TMAG5124 integrates a current source output 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 output enables robust communication between sensor and controller, helps detect disconnections, and limits the number of wires to two. Data can be transmitted over longer distances through this wire output.

The wide operating voltage range and reverse polarity protection of the TMAG5124 is designed for a variety of industrial applications.
