4.11.2
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.
4.11.3
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.
4.11.3.1
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.

1 All ESD testing is in conformity with CDF-AEC-Q100 Stress Test Qualification for Automotive Grade Integrated
Circuits.
2 A device will be defined as a failure if after exposure to ESD pulses the device no longer meets the device
specification requirements. Complete DC parametric and functional testing shall be performed per applicable
device specification at room temperature followed by hot temperature, unless specified otherwise in the device
specification.
