A1335

Precision Hall-Effect Angle Sensor IC

with ꢀ²C, SPI, and SENT Interfaces

FEATURES AND BENEFITS

DESCRIPTION

• 360° contactless high-resolution angle position sensor

• CVH (Circular Vertical Hall) technology

• Available with either a single die or dual independent die

housed within a single package

TheA1335isa360°contactlesshigh-resolutionprogrammable

magnetic angle position sensor IC. It is designed for digital

systems and is capable of communicating via an I²C, SPI, or

SENT interface.

• Digital output format selectable among SPI, I²C, and

SENT (Single-Edge Nibble Transmission)

• SENT output is SAEJ2716 JAN2010 compliant, with

Allegro proprietary enhanced programmable features

• Customer-programmable SENT tick times, ranging

from 0.5 to 7.9 µs

• SPI interface allows use of multiple independent sensor

ICs for applications requiring redundancy

• Refresh rate: 32 µs, 12-bit resolution

• Wide range of diagnostics enable automotive applications

to achieve ASIL-D compliance

• Programmable via Manchester encoding on the VCC

line, reducing external wiring

This system-on-chip (SoC) architecture includes a front

end based on Circular Vertical Hall (CVH) technology,

programmable microprocessor-based signal processing, and

featuresaninterfacecapableofsupportingI²C,SPI,andSENT.

Besides providing full-turn angular measurement, the A1335

also provides scaling for angle measurement applications less

than360^°.Itincludeson-chipEEPROMtechnology,capableof

supportingupto100read/writecycles,forflexibleprogramming

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 applications.

• Automotive temperature range: –40°C to 150°C

• AEC-Q100 automotive qualified

• Two types of linearization algorithms offered: harmonic

linearization and segmented linearization

TheA1335isidealforautomotiveapplicationsrequiringhigh-

speed 360° angle measurements, such as: electronic power

steering (EPS), transmission, torsion bar, and other systems

that require accurate measurement of angles. The A1335

linearizationschemesweredesignedwithchallengingoff-axis

applications in mind.

Packages:

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.
