Allegro MicroSystems Inc. 2D Dual-Channel Ultrasensitive Hall-Effect Latch A1262LK-X-T

Description
The A1262 is a two channel, latching Hall-effect sensor IC that features both vertical and planar Hall elements. The vertical and planar Hall elements feature sensing axes that are orthogonal to one another and provide 90° of phase separation for ring magnets that is inherently independent of magnet pole spacing and air gap. The 2D architecture of the A1262 simplifies the design of motors and magnetic encoders by providing quadrature output signals in a very small footprint. The A1262 outputs allow the speed and direction of a rotating ring magnet to be determined. The A1262 is available in two sensing options that allow flexibility in end-system magnetic design. Both options feature a planar Hall plate that is sensitive to magnetic fields perpendicular to the face of the package (Z). Two options of vertical Hall plate orientation (X or Y) in both packages offer flexibility in system design and magnet to sensor placement. On a single silicon chip, the A1262 includes: voltage regulator, reverse battery protection, two Hall plates (one planar and one vertical), a multiplexer, a small-signal amplifier, chopper stabilization, a Schmitt trigger, and two short-circuit protected open-drain outputs that can sink up to 20 mA continuously. The A1262 is available in two temperature ranges: –40°C to 85°C (E temperature range option) or –40°C to 150°C (L temperature range option). The A1262 is available in a 5-pin SOT23W surface-mount package (LH) and a 4 pin SIP package (K). Each is offered in two options for a variety of magnet to sensor orientations. The packages are RoHS compliant and lead (Pb) free, with 100% matte-tin leadframe plating.
