4. Application Notes
4.1. Application Circuit
For EMC protection, it is recommended to add each a
ceramic 4.7 nF capacitor between ground and the sup-
ply voltage respectively the output voltage pin. In addi-
tion, the input of the controller unit should be pulled-
down with a 4.7 kOhm resistor and a ceramic 4.7 nF
capacitor.
Please note that during programming, the sensor will
be supplied repeatedly with the programming voltage
of 12 V for 100 ms. All components connected to the
V
DD
line at this time must be able to resist this voltage.

4.2. Temperature Compensation
The relation between the temperature coefficient of the
magnet and the corresponding TC and TCSQ codes
for a linear compensation is given in the following
table. In addition to the linear change of the magnetic
field with temperature, the curvature can be adjusted,
too. For that purpose, TC and TCSQ have to be
changed to combinations that are not given in the
table. Please contact Micronas for more detailed infor-
mation.
