Additional Information:

Characterisation of Electro Magnetic Compatibility are carried out on sample base of one qualification lot.

Not all specification parameters have been monitored during EMC exposure. Only key parameters e.g.

switching current and duty cycle have been monitored.

Note: Test criteria for status A: No missing pulse no additional pulse on the IC output

signal plus duty cycle and jitter are in the specification limits.

Test criteria for status B: No missing pulse no additional pulse on the IC output

signal. (Output signal “OFF” means switching to the voltage of the pull-up resistor).

Test criteria for status C: One or more parameter can be out of specification during

the exposure but returns automatically to normal operation after exposure is

removed.

Test criteria for status E: destroyed.
