Worcester, MA – Allegro MicroSystems, LLC announces a new 360° contactless high-resolution programmable magnetic angle position sensor IC that has been designed for digital systems. Allegro’s A1335 device has a system-on-chip (SoC) architecture with a front-end based on Circular Vertical Hall (CVH) technology, programmable microprocessor-based signal processing, and supports multiple communication interfaces including I²C, SPI, and SENT.

In addition to providing 360° angular measurement, the A1335 also provides two options for on-chip linearization. It includes harmonic linearization to handle applications that require side-shaft magnetic configurations. The A1335 also supports segmented linearization that can be used for scaling angle measurement applications that require less than 360° of motion, so-called “short stroke” applications. It includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible programming of calibration parameters.

Digital signal processing functions, including temperature compensation and gain/offset trim, as well as advanced output linearization algorithms, provide an extremely accurate and linear output for both end-of-shaft applications as well as off-axis, or side-shaft, applications.

The A1335 is ideal for automotive applications requiring high-speed 360° angle measurements, such as: electronic power steering (EPS), transmission, torsion bar, and other systems that require accurate measurement of angles. The A1335 linearization schemes were designed with challenging off-axis applications in mind.

The A1335 is available as a single die in a 14-pin TSSOP, or dual die in a 24-pin TSSOP. Both packages are lead (Pb) free with 100% matte-tin leadframe plating.
