1.3. Marking Code
All Hall sensors have a marking on the package sur-
face (branded side). This marking includes the name
of the sensor and the temperature range.
Unipolar Inverted Switching Sensors:
The sensor turns to low current consumption with the
magnetic south pole on the branded side of the pack-
age and turns to high consumption if the magnetic field
is removed. The sensor does not respond to the mag-
netic north pole on the branded side.

Latching Sensor:
The sensor turns to high current consumption with the
magnetic south pole on the branded side of the pack-
age and turns to low consumption with the magnetic
north pole on the branded side. The current consump-
tion does not change if the magnetic field is removed.
For changing the current consumption, the opposite
magnetic field polarity must be applied.
1.4. Operating Junction Temperature Range (T

)
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature T
J
).

Note:
Due to the high power dissipation at high current
consumption, there is a difference between the
ambient temperature (T

) and junction tempera-
ture. Please refer to Section 5.4. on page 34 for
details.
