Two-Wire Hall-Effect Sensor Family
in CMOS technology
Release Note: Revision bars indicate significant
changes to the previous edition.
1. Introduction
– 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 ISO 7637
This sensor family consists of different two-wire Hall
switches produced in CMOS technology. All sensors
change the current consumption depending on the
external magnetic field and require only two wires
between sensor and evaluation circuit. The sensors of
this family differ in the magnetic switching behavior
and switching points.
The sensors include a temperature-compensated Hall
plate with active offset compensation, a comparator,
and a current source. The comparator compares the
actual magnetic flux through the Hall plate (Hall voltage) with the fixed reference values (switching points).
Accordingly, the current source is switched on (high
current consumption) or off (low current consumption).
The active offset compensation leads to constant magnetic characteristics in the full supply voltage and temperature range. In addition, the magnetic parameters
are robust against mechanical stress effects.
The sensors are designed for industrial and automotive applications and operate with supply voltages from
3.75 V to 24 V in the junction temperature range from
−40 °C up to 140 °C. All sensors are available in the
SMD package SOT89B-1 and in the leaded versions
TO92UA-1 and TO92UA-2.

1.6. Solderability and Welding
Solderability
During soldering reflow processing and manual
reworking, a component body temperature of 260 °C
should not be exceeded.
Welding
Device terminals should be compatible with laser and
resistance welding. Please note that the success of
the welding process is subject to different welding
parameters 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 component.

2. Functional Description
HAL57x, HAL58x
The HAL57x, HAL58x two-wire 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 temperaturedependent bias increases the supply voltage of the
Hall plates and adjusts the switching points to the
decreasing induction of magnets at higher temperatures.

Clock
If the magnetic field exceeds the threshold levels, the
current source switches to the corresponding state. In
the low current consumption state, the current source
is switched off and the current consumption is caused
only by the current through the Hall sensor. In the high
current consumption state, the current source is
switched on and the current consumption is caused by
the current through the Hall sensor and the current
source. The built-in hysteresis eliminates oscillation
and provides switching behavior of the output signal
without bouncing.
Magnetic offset caused by mechanical stress is compensated for by using the “switching offset compensation technique”. An internal oscillator provides a twophase clock. In each phase, the current is forced
through the Hall plate in a different direction, and the
Hall voltage is measured. At the end of the two
phases, the Hall voltages are averaged and thereby
the offset voltages are eliminated. The average value
is compared with the fixed switching points. Subsequently, the current consumption switches to the corresponding state. The amount of time elapsed from
crossing the magnetic switching level to switching of
the current level can vary between zero and 1/fosc.
Shunt protection devices clamp voltage peaks at the
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 protection
diode is needed for reverse voltages ranging from 0 V
to −15 V.

HAL584
DATA SHEET
4.7. HAL584
Applications
The HAL584 is a medium sensitive unipolar switching
sensor with an inverted output (see Fig. 4–25).
The HAL584 is designed for applications with one
magnetic polarity and weak magnetic amplitudes at
the sensor position where an inverted output signal is
required such as:
The sensor turns to low current consumption with the
magnetic south pole on the branded side of the package and turns to high current consumption if the magnetic field is removed. It does not respond to the magnetic north pole on the branded side.
– applications with large airgap or weak magnets,
– solid state switches,
– contactless solutions to replace micro switches,
For correct functioning in the application, the sensor
requires only the magnetic south pole on the branded
side of the package.
– position and end point detection, and
– rotating speed measurement.
In this two-wire sensor family, the HAL574 is a sensor
with the same magnetic characteristics but with a normal output characteristic.

5. Application Notes
5.2. Extended Operating Conditions
5.1. Application Circuit
All sensors fulfill the electrical and magnetic characteristics when operated within the Recommended Operating Conditions (see page 14).
Fig. 5–1 shows a simple application with a two-wire
sensor. The current consumption can be detected by
measuring the voltage over RL. For correct functioning
of the sensor, the voltage between pin 1 and 2 (VDD)
must be a minimum of 3.75 V. With the maximum current consumption of 17 mA, the maximum RL can be
calculated as:
R Lmax
Note: The functionality of the sensor below 3.75 V is
not tested on a regular base. For special test
conditions, please contact Micronas.
V SUPmin – 3.75 V
= ------------------------------------------17 mA
1 VDD
VSUP
5.3. Start-Up Behavior
VSIG
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 15). During the initialization time, the current consumption is not defined and can toggle between low
and high.
RL
2 or x GND
x = pin 3 for TO92UA-1/-2 package
x = pin 4 for SOT89B-1 package
HAL57x
Fig. 5–1: Application circuit 1
For applications with disturbances on the supply line or
radiated disturbances, a series resistor RV (ranging
from 10 Ω to 30 Ω) and a capacitor both placed close
to the sensor are recommended (see Fig. 5–2). In this
case, the maximum RL can be calculated as:
R Lmax
After ten(O), the current consumption will be high if the
applied magnetic field B is above BON. The current
consumption will be low if B is below BOFF.
HAL58x
In case of sensors with an inverted switching behavior,
the current consumption will be low if B > BOFF and
high if B < BON.

17 mA
Note: For magnetic fields between BOFF and BON, the
current consumption of the HAL sensor will be
either low or high after applying VDD. In order to
achieve a defined current consumption, the
applied magnetic field must be above BON,
respectively, below BOFF.

Typically, the sensors operate with supply voltages
above 3 V. However, below 3.75 V, the current consumption and the magnetic characteristics may be outside the specification.

5.4. Ambient Temperature
5.5. EMC and ESD
Due to internal power dissipation, the temperature on
the silicon chip (junction temperature TJ) is higher than
the temperature outside the package (ambient temperature TA).
For applications with disturbances on the supply line or
radiated disturbances, a series resistor and a capacitor
are recommended (see Fig. 5–3). The series resistor
and the capacitor should be placed as closely as possible to the HAL sensor.
T J = T A + ΔT
Applications with this arrangement passed the EMC
tests according to the product standards ISO 7637.
At static conditions and continuous operation, the following equation applies:
ΔT = IDD × VDD × R th
Please contact Micronas for detailed information and
first EMC and ESD results.

For all sensors, the junction temperature range TJ is
specified. The maximum ambient temperature TAmax
can be calculated as:

T Amax = T Jmax – ΔT
4.7 nF
2, x GND
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.
Due to the range of IDDhigh, self-heating can be critical.
The junction temperature can be reduced with pulsed
supply voltage. For supply times (ton) ranging from 30
μs to 1 ms, the following equation can be used:
x = pin 3 for TO92UA-1/-2 package
x = pin 4 for SOT89B-1 package
