A119x and A119x - F: programmable chopping stability two linear hall effect switch

A119x and A119x -f consisted of a series of two line unipolar hall effect switch can prep school at the end of the production by the user, to optimize the magnetic switch point accuracy in application.The latter (-f option) is the temperature compensation, these devices used in ferrite magnet with Allegro advanced BiCMOS wafer manufacturing processes, using its proprietary technology manufacturing high frequency four phase chopping stability.This technology can realize relative to all the magnetic stability of the operating temperature, eliminate the inherent deviation of single hall element device, suitable for harsh applications.

A119x and A119x - F series can meet the needs of many car application.These applications include induction seat adjustment guide position, belt buckles, hood/trunk locking and shifting the position of the selector.

Compared with the traditional open collector switch, two line unipolar switching less at work, with a thread so they are very suitable for the application of cost sensitive.Moreover, system designers can obtain diagnostic information all the time, because the output current must always be in two narrow range.Any is beyond the scope of the two current level indicates failure.

All products are provided in three types of packaging.LH is SOT - 23 w miniature flat surface mounting type packaging.UA is used for hole to install 3 pin ultra micro single straight plug-in package (SIP) UB is used for hole to install 2 pin ultra micro single straight plug-in package (SIP), and integrate the power decoupling capacitor.All three are lead (Pb) packaging, pin frame adopts 100% fog tin plating.
