Magnetic Offering From Infineon
Active error compensation - using a "chopped" Hall system - suppresses the effect of offset components. Resistance to electrostatic and electromagnetic interference has been designed in to make the new Hall sensors very cost-efficient and reliable.
The TLE49x6 family ICs were developed for use as position and proximity switches in wide variety of automotive subsystems, such as seat adjusters, seat-belt buckles, and electric windows and sunroofs. For example, the position of a seat can be sensed and the information sent to the air bag control mechanism to automatically tailor the deployment force to the size of the person - reducing the chance of injury being caused by the air bag.
The Hall switches incorporate the Hall sensor cell, bias generator, compensating circuit, comparator, oscillator and output transistor. The compensating circuits of the Hall switches balance out possible manufacturing process-related influences. At the same time, the sensor's active error compensation capability suppresses the effects of other voltage-generating mechanisms, such as mechanical stress, that may generate an offset to the Hall voltage and impair the measuring accuracy of the sensors.
Mechanical stress can be caused, for instance, by thermal influences, which occur as a result of further processing when soldered into the system or during over-moulding. The chopper technology, in conjunction with the integral comparator, ensures high-precision magnetic switching. All the members of the new TLE49x6 family of Hall sensors are now available in sample quantities, with series production scheduled to commence in Q3 2003. Infineon offers these new Hall sensors in space-saving packages - both in wired and surface-mounted technology.

AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
