The HAL5xx family consists of different Hall switches
produced in CMOS technology. All sensors include a
temperature-compensated Hall plate with active offset
compensation, a comparator, and an open-drain output
transistor. The comparator compares the actual magnetic flux through the Hall plate (Hall voltage) with the
fixed reference values (switching points). Accordingly,
the output transistor is switched on or off.
The sensors of this family differ in the switching behavior
and the switching points.
– switching offset compensation at typically 62 kHz
– operates from 3.8 V to 24 V supply voltage
– overvoltage protection at all pins
– reverse-voltage protection at VDD-pin
– magnetic characteristics are robust against mechanical stress effects
Latching Sensors:
– short-circuit protected open-drain output by thermal
shut down
The output turns low with the magnetic south pole on the
branded side of the package and turns high with the
magnetic north pole on the branded side. The output
does not change if the magnetic field is removed. For
changing the output state, the opposite magnetic field
polarity must be applied.
– operates with static magnetic fields and dynamic magnetic fields up to 10 kHz
– constant switching points over a wide supply voltage
range
– the decrease of magnetic flux density caused by rising
temperature in the sensor system is compensated by
a built-in negative temperature coefficient of the magnetic characteristics
– ideal sensor for applications in extreme automotive
and industrial environments
– EMC corresponding to DIN 40839

Hall sensors are available in a wide variety of packaging
versions and quantities. For more detailed information,
please refer to the brochure: “Ordering Codes for Hall
Sensors”.
During soldering reflow processing and manual reworking, a component body temperature of 260 °C should
not be exceeded.
Components stored in the original packaging should
provide a shelf life of at least 12 months, starting from the
date code printed on the labels, even in environments as
extreme as 40 °C and 90% relative humidity.

2. Functional Description
The HAL 5xx sensors are monolithic integrated circuits
which switch in response to magnetic fields. If a
magnetic field with flux lines perpendicular to the
sensitive area is applied to the sensor, the biased Hall
plate forces a Hall voltage proportional to this field. The
Hall voltage is compared with the actual threshold level
in the comparator. The temperature-dependent bias
increases the supply voltage of the Hall plates and
adjusts the switching points to the decreasing induction
of magnets at higher temperatures. If the magnetic field
exceeds the threshold levels, the open drain output
switches to the appropriate state. The built-in hysteresis
eliminates oscillation and provides switching behavior of
output without bouncing.
Magnetic offset caused by mechanical stress is compensated for by using the “switching offset compensation technique”. Therefore, an internal oscillator provides a two phase clock. The Hall voltage is sampled at
the end of the first phase. At the end of the second
phase, both sampled and actual Hall voltages are averaged and compared with the actual switching point. Subsequently, the open drain output switches to the appropriate state. The time from crossing the magnetic
switching level to switching of output can vary between
zero and 1/fosc.
Shunt protection devices clamp voltage peaks at the
Output-Pin and VDD-Pin together with external series
resistors. Reverse current is limited at the VDD-Pin by an
internal series resistor up to –15 V. No external reverse
protection diode is needed at the VDD-Pin for reverse
voltages ranging from 0 V to –15 V.

The output turns low with the magnetic south pole on the
branded side of the package and turns high with the
magnetic north pole on the branded side. The output
does not change if the magnetic field is removed. For
changing the output state, the opposite magnetic field
polarity must be applied.
– multipole magnet applications,
– rotating speed measurement,
– commutation of brushless DC motors, and
– window lifter.
For correct functioning in the application, the sensor requires both magnetic polarities (north and south) on the
branded side of the package.

4.11. HAL 518
Applications
The HAL 518 is a unipolar switching sensor with inverted
output (see Fig. 4–41).
The HAL 518 is the optimal sensor for applications with
one magnetic polarity where an inverted output signal is
required such as:
The output turns high with the magnetic south pole on
the branded side of the package and turns low if the
magnetic field is removed. The sensor does not respond
to the magnetic north pole on the branded side.
– solid state switches,
– contactless solution to replace micro switches,
– position and end point detection, and
– rotating speed measurement.
For correct functioning in the application, the sensor requires only the magnetic south pole on the branded side
of the package.

5. Application Notes
5.4. EMC and ESD
5.1. Ambient Temperature
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see figures 5–1). The series resistor
and the capacitor should be placed as closely as possible to the HAL sensor.
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 + ∆T
Applications with this arrangement passed the EMC
tests according to the product standards DIN 40839.
At static conditions, the following equation is valid:
∆T = IDD * VDD * Rth
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 – ∆T
5.2. Extended Operating Conditions
All sensors fulfill the electrical and magnetic characteristics when operated within the Recommended Operating
Conditions (see page 7).
Note: The international standard ISO 7637 is similar to
the used product standard DIN 40839.
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.
Fig. 5–1: Test circuit for EMC investigations
Note: The functionality of the sensor below 3.8 V has not
been tested. 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 ten(O)) after applying
the supply voltage. The parameter ten(O) is specified in
the Electrical Characteristics (see page 8).
During the initialization time, the output state is not defined and the output can toggle. After ten(O), the output
will be low if the applied magnetic field B is above BON.
The output will be high if B is below BOFF. In case of sensors with an inverted switching behavior (HAL 516 ...
HAL519), the output state will be high if B > BOFF and low
if B < BON.
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.
