Programmable angle sensor
(12)
If the magnetic field angle is larger than the CLAMP_SW_ANGLE, the output switches to
CLAMP_LO for a positive slope. The value of CLAMP_SW_ANGLE can be calculated
from other EEPROM constants but must be programmed.
14. Electromagnetic compatibility
EMC is verified in an independent and certified test laboratory.
14.1 Emission (CISPR 25)
Tests according to CISPR 25 were fulfilled.
14.1.1 Conducted radio disturbance
Test of the device according to CISPR 25, third edition (2008-03), Chapter 6.2.
Class: 5.
14.1.2 Radiated radio disturbance
Test of the device according to CISPR 25, third edition (2008-03), Chapter 6.4.
Class: 5 (without addition of 6 dB in FM band).
14.2 Radiated disturbances (ISO 11452-1 third edition (2005-02),
ISO 11452-2, ISO 11452-4 and ISO 11452-5)
The common understanding of the requested function is that an effect is tolerated as
described in Table 24
during the disturbance. The reachable values are setup dependent
and may differ from the final application.
14.2.1 Absorber lined shielded enclosure
Tests according to ISO 11452-2, second edition (2004-11), were fulfilled.
Test levels:
200 V/m; 200 MHz to 400 MHz (step 10 MHz)
200 V/m; 400 MHz to 1000 MHz (step 25 MHz)
200 V/m; 1 GHz to 10 GHz (step 100 MHz)
State: A.
