APPLICATION INFORMATION
Figure 10. Typical Current Waveform of IEC61000-4-2 ESD Generator
Machine Model
The Machine Model (MM) ESD test applies to all pins using a 200-pF capacitor with no discharge resistance.
The purpose of the MM test is to simulate possible ESD conditions that can occur during the handling and
assembly processes of manufacturing. In this case, ESD protection is required for all pins, not just RS-232 pins.
However, after PC board assembly, the MM test is no longer as pertinent to the RS-232 pins.
