MLX90288
SMD Programmable Linear Hall Sensor IC
Featuring Analog Ratiometric Output
The factory calibration performed by Melexis targets a specific magnet TC, which serves as accurate basis
for any delta calibration that should be performed when using a magnet with a different TC. This is performed
via the solver software provided by Melexis. The TEMPOFF parameter defines for which temperature the
gain compensation should be 1 (i.e. no compensation), whereas the TEMPTC parameter defines which
temperature range of the curve presented in Figure 3 is mapped onto the application temperature range.
Higher TEMPTC codes will use a bigger range, which corresponds to more gain compensation and thus
bigger magnet temperature coefficients.
