2.3 Principle of Operation
General
• A magnetic flux is measured by a Hall-effect cell
• The output signal from the Hall-effect cell is converted from analog to digital signals
• The chopped Hall-effect cell and continuous-time A/D conversion ensure a very low and stable magnetic offset
• A programmable low-pass filter to reduce noise
• The temperature is measured and A/D converted
• Temperature compensation is done digitally using a second-order function
• Digital processing of the output value is based on zero field and sensitivity value
• The output value range can be clamped by digital limiters
• The final output value is represented by the data nibbles of the SPC protocol
2.4 Further Notes
Product qualification is based on “AEC Q100 Rev. G” (Automotive Electronics Council - Stress test qualification
for integrated circuits).
2.5 Transfer Functions
The examples in Figure 2-2 show how different magnetic field ranges can be mapped to the desired output value
ranges.
• Polarity Mode:
– Bipolar: Magnetic fields can be measured in both orientations. The limit points do not necessarily have to
be symmetrical around the zero field point
– Unipolar: Only north- or south-oriented magnetic fields are measured
• Inversion: Both gain can be set to positive values, negative values or positive/negative values.
