5. Application Notes
5.1. Application Circuit
The HAL11x sensors can operate without external com-
ponents. For applications with disturbances on the sup-
ply line or radiated disturbances, a series resistor and a
capacitor are recommended (see Fig. 5–1).
The series resistor and the capacitor should be placed
as closely as possible to the sensor.

5.2. Ambient Temperature
Due to the internal power dissipation, the temperature
on the silicon chip (junction temperature T
J
) is higher
than the temperature outside the package (ambient tem-
perature T
A
).

For typical values, use the typical parameters. For worst

For all sensors, the junction temperature range T

specified. The maximum ambient temperature T

5.3. Extended Operating Conditions
All sensors fulfill the electrical and magnetic characteris-
tics when operated within the Recommended Operating
Conditions (see page 6).
Please use the sensors of the HAL 5xx family if lower op-
eration voltage, lower current consumption or tighter
magnetic specifications required.
5.4. Start-up Behavior
The sensors have an initialization time (enable time
t
en(O)
) after applying the supply voltage. This parameter
t
en(O)
is specified in the Electrical Characteristics (see
page 7).
During the initialization time, the output state is not de-
fined and can toggle. After t
en(O)
, the output will be low
if the applied magnetic field B is above B
ON
or high if B
is below B
OFF
.
For magnetic fields between B
OFF
and B
ON
, the output
state of the HAL sensor after applying V
DD
will be either
low or high. In order to achieve a well-defined output
state, the applied magnetic field must be above B
ONmax
,
respectively, below B
OFFmin
.
