3.11.2

Electromagnetic interference (EMI)

The product is monitored in terms of emission based on a typical application. This emission

test conforms to the IEC61967-1 standard, which specifies the general conditions for EMI

measurements.

3.11.3

Absolute maximum ratings (electrical sensitivity)

Based on two different tests (ESD and LU) using specific measurement methods, the

product is stressed in order to determine its performance in terms of electrical sensitivity.

3.11.3.1

Electrostatic discharge (ESD)

Electrostatic discharges (a positive then a negative pulse separated by 1 second) are

applied to the pins of each sample according to each pin combination. The sample size

depends on the number of supply pins in the device (3 parts (n+1) supply pin). This test

conforms to the AEC-Q100-002/-003/-011 standard. For more details, refer to the

application note Electrostatic Discharge Sensitivity Measurement (AN1181).
