+title: TI TMAG5273 Low-Power Linear 3D Hall-Effect Sensor
+
+maintainers:
+ - Gerald Loacker <gerald.loacker@wolfvision.net>
+
+description:
+ The TI TMAG5273 is a low-power linear 3D Hall-effect sensor. This device
+ integrates three independent Hall-effect sensors in the X, Y, and Z axes.
+ The device has an integrated temperature sensor available. The TMAG5273
+ can be configured through the I2C interface to enable any combination of
+ magnetic axes and temperature measurements. An integrated angle calculation
+ engine (CORDIC) provides full 360° angular position information for both
+ on-axis and off-axis angle measurement topologies. The angle calculation is
+ performed using two user-selected magnetic axes.
