Functional Description
Measurement Principle
A hall sensor array is used to convert the magnetic field distribution above the chip surface into
a binary code.
Measurement is enabled by PD/CS=0. After each measurement a 6-bit value is latched, with
the first falling edge of the CLK, into an output shift register.
The measured data is accessible via a Synchronous Serial Interface (SSI) by any
μ
Controller
System.
Ratiometric measurement techniques together with hall sensor conditioning circuitry allow
robust tolerance to magnet misalignment.
Permanent Encoder Magnet
A simple two-pole magnet, e.g. a standard cylindrical permanent magnet that is diametric
magnetised, is needed.
Magnetic Field strength of at least
±
30mTp is required at the package surface.
Standard magnet materials like rare earth AlNiCo / SmCo5 or NdFeB are recommended.
