MICRONAS SEMICONDUCTOR HOLDING AG : Micronas set to enlarge its 3D Hall sensor … – 4

Freiburg, December 21, 2011 – Micronas (SIX Swiss Exchange:
MASN), a leading supplier of cutting-edge sensor and IC
system solutions for automotive and industrial electronics,
invests in the development of new sensors of the HAL 36xy
and HAL 38xy families and so enlarges its product portfolio
in the field of multi-dimensional magnetic field
detection.

Unlike standard magnet field measurements which only
capture and detect magnetic fields whose field lines run
orthogonally to the chip surface, the HAL 36xy and HAL 38xy
sensor families with their additional vertical Hall boards
also detect magnetic field components of the magnetic field
running parallel to the surface. The vertical Hall boards
have the advantage that they can be made using a standard
CMOS process without additional post-processing and that
they are not influencing the magnetic field itself.

The members of the Hall sensor families based on 3D Hall
technology all feature temperature-compensated Hall boards
with cycled offset compensation, A/D transformers, digital
signal processing, a push-pull output, an EEPROM with
redundant memory cells and write protection for the
calibration data and the data registry information, a
digital programming interface as well as additional
switching components realizing diagnosis functions and so
enhancing the safety of the aggregate system such as
temperature and voltage monitoring (under and overvoltage),
open-circuit detection and overload protection in all
connections. Additional functions such as an EEPROM
self-test during system start can be activated by the
customer.

The sensors of the HAL 36xy family detect the magnetic
field components in the X and Y level in three-dimensional
space. Measuring the relative field strength of both
components guarantees a stable output signal even if the
space between magnet and sensor varies. The result is a
highly precise angular measurement between 0° and 360°,
working reliably across a wide temperature range. The HAL
3625 is, for instance, suitable for applications involving
non-contacting potentiometers or for determining the
position in rotary movements, and therefore features an
analogue output signal with 12 bit resolution.

Within the HAL 38xy family, the HAL 3855 module is capable
of detecting the magnetic field strength at the Y and Z
level. 32 backing points lend this sensor family ultimate
accuracy in linear motion measurements with minimum space
requirement. The HAL 3855 is, for example, suitable for
detecting the throttle position in exhaust gas
recirculation (EGR) in cars and also features an analogue
output signal with 12 bit resolution.

Micronas currently develops various sensor variants based
on the 3D HAL technology by way of an extension to the HAL
36xy und HAL 38xy families. These will include sensors with
digital output, with design variants relying on various
combination options involving the Hall boards (X, Y and Z
level) also being under development.

With the extremely broad temperature range of Tj = -40°C to
+170°C (junction temperature), many new application options
in the automobile and industrial electronics industry open
up for the derivatives of the HAL 36xy and HAL 38xy sensor
families, among these the detection of throttle positions
with angles greater than 90° or in the measurement of
linear movements with distances of as much as 40 mm.

The HAL 3855 and HAL 3625 sensors are so far available in
the exceedingly small SMD enclosure SOIC8. This is also an
area where Micronas has plans for future expansion.
