New Linear Hall Sensors from Micronas offering cost benefits through preset sensitivity levels

Low-cost magnetic field sensors with ultimate reliability for use in automobile, domestic and industrial applications

(PresseBox) (Freiburg, ) Micronas (SIX Swiss Exchange: MASN), a leading manufacturer and supplier of innovative and userspecific IC and sensor system solutions for use in automobiles and in industry, presents three new valueoptimized variants of the HAL 182x family.

"The linear Hall sensors HAL 1821, HAL 1822 and HAL 1823 are available with different levels of sensitivity to match application requirements. In contrast to the HAL 1820, the programming functionality has been dropped with the new types in order to achieve the better priceperformance ratio.

The sensors can be used to determine position, direction of motion, fluid level and for current measurements. They can also be used to replace classic potentiometers", says Peter Zimmermann, Director Marketing at Micronas.

HAL 1821, HAL 1822 and HAL 1823 are designed for use in automobiles, with superior EMC performance and with internal overvoltage and reverse voltage protection at the power supply pins.

An application board is available for the development. The Hall sensors are offered in TO92UA and SOT89A housings and aim for the temperature range TJ = -40 °C to +170 °C, with several temperature classes available within this range. Depending on type, the sensors are on offer at a price between EUR 0.65 and 0.75 at unit quantities of 100k. Samples in the TO92UA housing are available within the second quarter of 2010.

Micronas will present the HAL 1821, HAL 1822 and HAL 1823 sensors at the "embedded world 2010" fair in Nuremberg (Hall 12, Stand 236) from 2nd until 4th of March.


Micronas today offers the world's broadest range of Halleffect sensors. A Halleffect sensor detects the presence of a magnet without requiring actual physical contact. Thus, it can be used to sense movement and rotation without requiring contact with the moving object. Other parameters like pressure, force or torque can be sensed by noting the slight movements of a magnet caused by changes of the applied parameter.

While Halleffect sensors can be made from various materials, Micronas pioneered the market in CMOS Halleffect sensors and was the first to manufacture in CMOS technology. This technology allows integration of the Halleffect sensing element with standard electronic devices such as amplifiers, logic circuits, and volatile and nonvolatile memories.

Micronas' expertise in Hall sensors combines perfectly with its CMOS and mixedsignal design resources to create accurate, intelligent sensors for a broad range of applications. The everincreasing demand for energyefficient and highly reliable machines means that demand for these smart sensors will continue to grow.
