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.
