Figure 2. Timing of VP and VM to D+ and D-
stand voltage measured to IEC 61000-4-2 generally is
lower than that measured using the Human Body
Model. Figure 8 shows the IEC 61000-4-2 model. The
Contact Discharge method connects the probe to the
device before the probe is charged.
The Machine Model for ESD tests all connections using
a 200pF storage capacitor and zero discharge resis-

tance. Its objective is to emulate the stress caused by
contact that occurs with handling and assembly during
manufacturing. All pins require this protection during
manufacturing, not just inputs and outputs. After PC
board assembly, the Machine Model is less relevant to
I/O ports.
