Micronas Presents ESD-proof Linear Hall Sensors Of The Latest Generation For Precise Measurement Of Low Magnetic Fields
May 13 2013 - 4:48AM
Micronas (SIX Swiss Exchange:MASN), known and recognized in the
automotive and industrial business as a global partner for
intelligent, sensor-based system solutions, today presents the HAL
835 as first member of the new HAL 83x family. With these highly
precise magnetic field sensors of the latest generation Micronas
brings unique sensor solutions to the market. Micronas enables its
customers the use of Linear Hall sensors under most demanding
environmental conditions with highest reliability. "With this new
Hall sensor family, Micronas now covers all application fields for
Linear sensors on the market. The HAL 835 represents the ideal
solution for the measurement of linear movement, position
detection, current measurement, or for use as contactless
potentiometer", explains Dirk Behrens, Vice President Automotive at
Micronas. The HAL 835 was developed as a response to newest market
trends. These trends include the demands of the automotive industry
for higher ESD protection of the sensors, the increased use of
smaller magnets and thus lower magnetic field strengths, as well as
the need for even more accurate measurements of parameters in the
power train due to more stringent emission standards. With the HAL
835 sensor Micronas is answering to all of these demands. The
adjustable, smallest measurement range of HAL 835 could be extended
to ±15 mT while the resolution is still 12 bit (7.5 µT / bit).
Compared to its predecessor HAL 825, offset and sensitivity drift
have been further reduced. With a differential nonlinearity (DNL)
of less than 0.9 LSB Micronas fulfills highest demands to the
measurement precision. Furthermore, the bandwidth of the internal
filter has been extended. Beside customers' most frequently
requested output formats (analog/PWM) the HAL 835 offers another
format: multiplex-analog. This, thanks to the separate transmission
of the MSB and LSB part of the measurement signal, features an
increased signal-to-noise ratio. In addition, the implemented
digital back-bias cancellation reduces the influence of interfering
static magnetic fields. This allows the execution of highly precise
measurements. The compact design of modern combustion engines leads
to increasing demands of the temperature behavior to the sensing
parts. Here, Micronas relies on its long-term proven CMOS
technology. Devices produced on the basis of this technology are
designed for junction temperatures up to 170 °C. The HAL 835 has an
integrated EEPROM for the storage of the sensor parameters, which
works reliably up to 170 °C, as well. These features provide the
HAL 835 with the needed precision for detecting the position of
throttle valves of the next generation in vehicles for instance.
Thus, the sensor contributes to less fuel-consumption as well as to
reduced CO2 emissions. With the delivery of the devices in the
"green package" according to the RoHS directive, Micronas commits
itself to sustainable environmental protection. The HAL 83x sensors
are produced in the mouldable TO92UT package. First samples of the
HAL 835 are available as of today. Start of production is planned
for the end of the third quarter 2013. For evaluation and fast
integration into customer applications, Micronas offers a special
programming board. The needed software is provided free of charge.
Micronas will present the HAL 835 from May 14 to 16, 2013 at the
Sensor+Test in Nuremberg (hall 12, booth 302).
