Unipolar Inverted Switching Sensors:
1.3. Marking Code
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.
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.

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 (TJ)
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature TJ).
K: TJ = −40 °C to +140 °C
E: TJ = −40 °C to +100 °C
Current consumption
IDDhigh
Note: Due to the high power dissipation at high current
consumption, there is a difference between the
ambient temperature (TA) and junction tempera-
ture. Please refer to Section 5.4. on page 34 for
details.
