12 description:
13 The TI TMAG5273 is a low-power linear 3D Hall-effect sensor. This device
14 integrates three independent Hall-effect sensors in the X, Y, and Z axes.
15 The device has an integrated temperature sensor available. The TMAG5273
16 can be configured through the I2C interface to enable any combination of
17 magnetic axes and temperature measurements. An integrated angle calculation
18 engine (CORDIC) provides full 360° angular position information for both
19 on-axis and off-axis angle measurement topologies. The angle calculation is
20 performed using two user-selected magnetic axes.
