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.

1.3. 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.

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

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.
