1.2. Marking Code
All Hall sensors have a marking on the package
surface (branded side). This marking includes the
name of the sensor and the temperature range.

1.3. Operating Junction Temperature Range
The Hall sensors from Micronas are specified to the
chip temperature (junction temperature TJ).
I: TJ = −20 °C to +125 °C
C: TJ = 0 °C to +85 °C

ing versions and quantities. For more detailed informa-
tion, please refer to the brochure: “Hall Sensors.

1.4. Solderability and Welding
Soldering
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.
Welding
Device terminals shall be compatible with laser and
electrical welding. Please, note that the success of the
welding process is subject to different welding parame-
ters which will vary according to the welding technique
used. A very close control of the welding parameters is
absolutely necessary in order to reach satisfying
results. Micronas, therefore, does not give any implied
or express warranty as to the ability to weld the com-
ponent.

3. Application Notes
3.1. Ambient Temperature
Due to the internal power dissipation, the temperature
on the silicon chip (junction temperature TJ) is higher
than the temperature outside the package (ambient
temperature TA).
TJ = TA + ΔT
At static conditions and continuous operation, the fol-
lowing equation applies:
ΔT = IDD × VDD × Rth
If IOUT > IDD, please contact Micronas application sup-
port for detailed instructions on calculating ambient
temperature.
For typical values, use the typical parameters. For
worst case calculation, use the max. parameters for
IDD and Rth, and the max. value for VDD from the
application.
For all sensors, the junction temperature range TJ is
specified. The maximum ambient temperature TAmax
can be calculated as:
TAmax = TJmax – ΔT
3.2. Extended Operating Conditions
All sensors fulfill the electrical and magnetic character-
istics when operated within the Recommended Oper-
ating Conditions (see page 8).
3.3. Start-up Behavior
Due to the active offset compensation, the sensors
have an initialization time (enable time ten(O)) after
applying the supply voltage. The parameter ten(O) is
specified in Section 2.5.: Characteristics on page 9.
During the initialization time, the output state is not
defined and the output can toggle. After ten(O), the out-
put will be low if the applied magnetic field B is above
BON. The output will be high if B is below BOFF.
For magnetic fields between BOFF and BON, the output
state of the HAL sensor after applying VDD will be
either low or high. In order to achieve a well-defined
output state, the applied magnetic field must be above
BONmax, respectively, below BOFFmin.
3.4. EMC and ESD
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see Fig. 3–1). The series resistor
and the capacitor should be placed as closely as
possible to the HAL sensor.
Please contact Micronas for the detailed investigation
reports with the EMC and ESD results.

Supply Voltage Below 3.8 V
Typically, the sensors operate with supply voltages
above 3 V, however, below 3.8 V some characteristics
may be outside the specification.
Note: The functionality of the sensor below 3.8 V is
not tested. For special test conditions, please
contact Micronas.
