Micronas Presents High-Sensitivity Current Transducer for Use in Automotive and Industrial Applications
October 25 2012 - 6:07AM
Micronas (SIX Swiss Exchange:MASN), known and recognized in the
automotive and industrial business as a reliable and global partner
for intelligent, sensor-based solutions for automotive and
industrial applications, presents its CUR 3115, the most recent
member of the CUR 31xy current transducer family basing its
measuring principle on the Hall effect. The CUR 3115 with its
enhanced sensitivity and its space-saving SMD package is especially
predestined for all current measurements on circuit-board
conductors. The enhanced sensitivity is accomplished by an
advantageous positioning ("die down") of the sensor chip inside the
package, which substantially reduces the space between the Hall
element and the measured object (circuit-board conductor). Compared
to its predecessor CUR 3105, the CUR 3115 as well offers a lower
sensitivity drift over the whole temperature range, achieving under
optimum conditions a measuring error of below one percent.
Parameters for controlling the resolution and the temperature
behaviour can be stored in an EEPROM with redundancy function. Like
its predecessor, the CUR 3115 is programmable with ultimate
flexibility and equipped with an analog output. With their new
generation of engines, car makers today put the focus on the
development of fuel-saving and clean petrol engines. Promising
approaches include smaller cubic capacities and fewer cylinders,
with the drawbacks being a loss of vehicle performance and reduced
ride comfort, and especially weaker torques at lower engine speeds.
To compensate these shortcomings, more efficient and
power-supported charging systems such as the E-Booster by
Continental are used today beside the common known turbo chargers.
The above mentioned E-Booster makes already use of the advantages
of the presented CUR 3115 and has been honoured in February 2011,
with the "Yellow Angel" award in the "Innovation and Environment"
category from the ADAC (German automobile association). The CUR
3115 also addresses applications such as battery monitoring, for
instance in hybrid or electric cars, but also in start-stop systems
in modern, fuel-efficient vehicles or in induction cookers.
Combined with a ferro-magnetic flux concentrator, the CUR 31xy
family is also capable of detecting electric currents down to the
milliampere range. Currents of 50A and higher can be measured
without using a flux concentrator. The current transducers have a
bandwidth of up to 1 kHz and a usable magnetic field range from ±30
to ±100 mT. The CUR 31xy family is available in the small SOIC8
package capable of being soldered and welded. The CUR 31xy family
works in the temperature range from TJ = -40 to 140°C. For
increased safety it includes an additional built-in detection of
overvoltages and a reverse voltage protection of the supply
connection. Micronas will present the CUR 3115 at the "electronica"
in Munich (Hall A6, Booth 215) from November 13 to 16.
About sensor solutions from Micronas
Micronas today offers the world's broadest range of Hall-effect
sensors and pioneered Hall sensors in CMOS technology. The company
was the first to market CMOS Hall sensors. This technology allows
the integration of the Hall-effect sensing element with standard
electronics devices such as amplifiers, logic circuits, and
volatile or non-volatile memories. Micronas' expertise in Hall
sensors combines perfectly with its CMOS and mixed-signal design
resources to create accurate, intelligent sensors for a broad range
of applications. The ever-increasing demand for energy-efficient
and highly reliable machines means that demand for these smart
sensors will continue to grow. About Micronas
Micronas (SIX Swiss Exchange:MASN) is known and recognized in
the automotive and industrial business as a reliable global partner
for intelligent, sensor-based system solutions. Micronas offers a
variety of Hall sensors and embedded controllers for smart
actuators for automotive and industrial applications, such as drive
trains, chassis frames, engine management and convenience
functions. Micronas serves all major automotive electronics
customers worldwide, many of them in continuous partnerships
seeking joint success. While the holding company is headquartered
in Zurich (Switzerland), operational headquarters are based in
Freiburg (Germany). Currently, the Micronas Group employs around
900 persons. For more information about Micronas and its products,
