5. Application Notes
5.1. Application Circuit
Figure 5–1 shows a simple application with a two-wire
sensor. The current consumption can be detected by
measuring the voltage over R
L
. For correct functioning
of the sensor, the voltage between pin 1 and 2 (V
DD
)
must be a minimum of 4 V. With the maximum current
consumption of 17 mA, the maximum R
L
can be calcu-
lated as:

Application Circuit 1
For applications with disturbances on the supply line or
radiated disturbances, a series resistor R
V
(ranging from
10
to 30
)
and a capacitor both placed close to the
sensor are recommended (see figure 5–2). In this case,
the maximum R
L
can be calculated as:

5.2. Extended Operating Conditions
All sensors fulfill the electrical and magnetic characteris-
tics when operated within the Recommended Operating
Conditions (see page 7).
Typically, the sensors operate with supply voltages
above 3 V. However, below 4 V, the current consumption
and the magnetic characteristics may be outside the
specification.
Note:
The functionality of the sensor below 4 V is not
tested on a regular base. For special test conditions,
please contact Micronas.
5.3. Start-up Behavior
Due to the active offset compensation, the sensors have
an initialization time (enable time t
en(O)
) after applying
the supply voltage. The parameter t
en(O)
is specified in
the Electrical Characteristics (see page 8). During the
initialization time, the current consumption is not defined
and can toggle between low and high.
HAL556:
After t
en(O)
, the current consumption will be high if the
applied magnetic field B is above B
ON
. The current con-
sumption will be low if B is below B
OFF
.
HAL560, HAL566:
In case of sensors with an inverted switching behavior,
the current consumption will be low if B > B
OFF
and high
if B < B
ON
.
Note:
For magnetic fields between B
OFF
and B
ON
, the
current consumption of the HAL sensor will be either low
or high after applying V
DD
. In order to achieve a defined
current consumption, the applied magnetic field must be
above B
ON
, respectively, below B
OFF
.
