9.6.3

Electromagnetic interference (EMI)

Emission tests conform to the IEC61967-2 standard for board layout and pin loading. Worse

case EMI measurements are performed during maximum device activity.

9.6.4

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.

For more details, refer to the application note AN1181.

9.6.5

Electrostatic discharge (ESD)

Electrostatic discharges (3 positive then 3 negative pulses 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 JESD22-A114A/A115A standard. For more details, refer to the application

note AN1181.
