+title: TI TMAG5273 Low-Power Linear 3D Hall-Effect Sensor
+
+maintainers:
+ - Gerald Loacker <gerald.loacker@...fvision.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.

+ A regulator providing 1.7 V to 3.6 V supply voltage on the VCC pin,
+ typically 3.3 V.

+ description:
+ The low active interrupt can be configured to be fixed width or latched.
+ Interrupt events can be configured to be generated from magnetic
+ thresholds or when a conversion is completed.
