Productomschrijving

Dual element devices are integrated circuits that contain two independent Hall-effect switches. The digital outputs are out-of-phase (quadrature) when interfaced with the proper ring magnet design. These quadrature signals can be processed to determine target speed and direction. Alternately, the A1232 and A1233 internally process these switch outputs into speed and direction signals. The revolutionary A1262 uses a combination of vertical and planar Hall elements to sense in two dimensions (2D), delivering near-ideal quadrature signals independent of the magnet pole pitch. This, combined with its small size, greatly simplifies system design. Extremely low-drift amplifiers guarantee symmetry between the switches to maintain signal quadrature. The Allegro high-frequency, chopper stabilization technique cancels offsets in each channel, providing stable operation over the full specified temperature and voltage ranges, and industry-leading digital output jitter performance that is critical in high-performance motor commutation applications

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
