The TMAG5213 is a low-cost, chopper-stabilized Hall-effect sensor with excellent sensitivity stability over temperature and integrated protection features.
The magnetic field is indicated through a digital bipolar latch output. When the applied magnetic flux density crosses the operating point (BOP) threshold, the device outputs a low voltage. The output stays low until the flux density crosses the release point (BRP), at which point the device output gets pulled high. This bipolar latch magnetic response allows the device output to be sensitive to positive and negative magnetic flux through the Z-axis of the package.
The TMAG5213 has a wide operating voltage range from 2.5V to 28V and operating temperature range from –40°C to +125°C designed for a variety of industrial applications. Internal protection functions are provided for output short circuit or overcurrent, and the device has an open-drain output stage with 30mA current sink capability.
