A1262LK-Y-T

Allegro's A1262 integrated circuit is a 2D ultra-sensitive Hall-effect latch. It features operation with traditional planar magnetic field direction as well as vertical sensing direction. The dual operation of the planar and vertical Hall elements allows the end user to achieve 90° of phase separation that is inherently independent of magnetic pole spacing. The quadrature outputs of the A1262 allows rotation direction to be determined, such as when sensing a rotating ring-magnet target. This device is targeted for the automotive, industrial and instrumentation markets in motor commutation applications such as window lift, sunroof, sliding doors, and trunk and tail gate lifts.
