Reference design standard tests

Figure 40 describes the protection intervention in case of differential mode disturbances.

A differential voltage higher than 15 V p-p is clamped by the D1 bidirectional Transil™

diode. The D1 is the most robust protection and also the one that is able to absorb most of

the energy of any incoming disturbance.

PRIME pre-compliance tests

Minimum output level over PRIME LISN

The ST7590 reference design is capable to provide a 121 dBµV over PRIME LISN, thus

complying with the 120 dBµV minimum level set by PRIME specifications.

Note that, as indicated by PRIME specifications, the measurement result is 6 dB lower than

the actual value, being it measured between the line and ground (half signal power).
