General Description

The TMAG5231 is a 2nd-generation, low-power Halleffect switch sensor, specifically designed to optimize the total system cost for compact, battery-operated consumer and industrial applications.

When the applied magnetic flux density exceeds the operating point (BOP) threshold, the device outputs a low voltage.

The output stays low until the flux density decreases to less than the release point (BRP), and then the device outputs a high voltage.
