Hall Effect Sensor Family
in CMOS technology
Release Notes: Revision bars indicate significant
changes to the previous edition.
1. Introduction
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 mag-
netic 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.
The active offset compensation leads to constant mag-
netic characteristics over supply voltage and tempera-
ture range. In addition, the magnetic parameters are ro-
bust against mechanical stress effects.
The sensors are designed for industrial and automotive
applications and operate with supply voltages from
3.8 V to 24 V in the ambient temperature range from
–40 °C up to 150 °C.
All sensors are available in a SMD-package (SOT-89B)
and in a leaded version (TO-92UA).
1.1. Features:
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 mechani-
cal stress effects
short-circuit protected open-drain output by thermal
shut down
operates with static magnetic fields and dynamic mag-
netic 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 mag-
netic characteristics
ideal sensor for applications in extreme automotive
and industrial environments
EMC corresponding to DIN 40839
1.2. Family Overview
The types differ according to the magnetic flux density
values for the magnetic switching points, the tempera-
ture behavior of the magnetic switching points, and the
mode of switching.

Latching Sensors:
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.
Bipolar Switching Sensors:
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
state is not defined for all sensors if the magnetic field is
removed again. Some sensors will change the output
state and some sensors will not.

1.3.1. Special Marking of Prototype Parts
Prototype parts are coded with an underscore beneath the
temperature range letter on each IC. They may be used
for lab experiments and design-ins but are not intended to
be used for qualification tests or as production parts.
1.4. Operating Junction Temperature Range
A: TJ = 40 °C to +170 °C
K: TJ = 40 °C to +140 °C
E: TJ = 40 °C to +100 °C
The Hall sensors from Micronas are specified to the chip
temperature (junction temperature TJ).
The relationship between ambient temperature (TA) and
junction temperature is explained in section 5.1. on page
40.

please refer to the brochure: Ordering Codes for Hall
Sensors.
1.6. Solderability
all packages: according to IEC68-2-58
During soldering reflow processing and manual rework-
ing, 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 HAL5xx 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 com-
pensated for by using the switching offset compensa-
tion technique. Therefore, an internal oscillator pro-
vides 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 aver-
aged and compared with the actual switching point. Sub-
sequently, the open drain output switches to the ap-
propriate 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.

4. Type Description
4.1. HAL501
The HAL501 is the most sensitive sensor of this family
with bipolar switching behavior (see Fig. 41).
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
state is not defined for all sensors if the magnetic field is
removed again. Some sensors will change the output
state and some sensors will not.
For correct functioning in the application, the sensor re-
quires both magnetic polarities (north and south) on the
branded side of the package.
Magnetic Features:
switching type: bipolar
very high sensitivity
typical BON: 0.5 mT at room temperature
typical BOFF: 0.7 mT at room temperature
operates with static magnetic fields and dynamic mag-
netic fields up to 10 kHz
Applications
The HAL 501 is the optimal sensor for all applications
with alternating magnetic signals and weak magnetic
amplitude at the sensor position such as:
applications with large airgap or weak magnets,
rotating speed measurement,
CAM shaft sensors, and
magnetic encoders.

5. Application Notes
5.1. 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 tem-
perature TA).
TJ = TA + T
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 characteris-
tics when operated within the Recommended Operating
Conditions (see page 7).
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 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 de-
fined 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 sen-
sors with an inverted switching behavior (HAL516 ...
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.
5.4. EMC and ESD
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see figures 51). The series resistor
and the capacitor should be placed as closely as pos-
sible to the HAL sensor.
Applications with this arrangement passed the EMC
tests according to the product standards DIN 40839.
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.
