Temperature Coefficient Register
Offset temperature compensation
The TLE5012B compensates the temperature dependence of the X- and Y-offsets during run-time by using an
integrated temperature measurement (see register TEMPER on
) and applying factory-calibrated
temperature coefficients for the offsets. At a chip temperature of T, the resulting offset correction parameters are
given by:
(6.7)
Temperature compensation of the offsets is only active, if autocalibration is disabled. If auto-calibration is enabled,
TCO_X_T and TCO_Y_T are automatically set to 0. Once auto-calibration is deactivated, laser-fused calibration
values are loaded into TCO_X_T and TCO_Y_T.

Offset Temperature Coefficient for Y-Component
7-bit signed integer value of Y-offset temperature
coefficient. This register is used both with autocalibration
and without autocalibration. If autocalibration is
deactivated, overwrite only with the default value. If
autocalibration is activated, do not write this bitfield. See
“Offset temperature compensation” on Page 97
