A1262LLHLX-X-T

The A1262 is a dual-channel latching Hall-effect sensor IC featuring both vertical and planar Hall elements. The sensing axes of the vertical and planar Hall elements are orthogonal to each other, providing 90° phase separation for ring magnets regardless of pole pitch and air gap. The A1262's two-dimensional architecture simplifies motor and magnetic encoder design by delivering orthogonal output signals within a minimal footprint. Its outputs can be used to determine the speed and direction of a rotating ring magnet. The A1262 offers two sensing options, providing flexibility in magnetic circuit design for end systems. Both options include a planar Hall plate sensitive to magnetic fields perpendicular to the package surface (Z). Two orientations of the vertical Hall plate (X or Y) are available across the two packages, offering flexibility in system design and magnet-to-sensor placement. On a single silicon die, the A1262 integrates: a 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 capable of continuously sinking up to 20mA. 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 offered in a 5-pin SOT23W SMT package (LH) and a 4-pin SIP package (K). Each package is available in two options to accommodate various magnet-to-sensor orientations. These packages are RoHS-compliant and lead-free, with lead frames finished in 100% matte tin plating.
