Enhanced VGA Port Protector
ESD protection can be tested in various ways. The RED,
GRN, BLU, EN , V S , SYNCH1, SYNCV1, SCL1, and SDA1
terminals of the device are characterized for protection to
the following limits:
? Q 15kV using the HBM
? Q 8kV using IEC 61000-4-2 Contact Discharge
Human Body Model
Figure 2 shows the HBM. Figure 3 shows the current
waveform it generates when discharged into a low-
impedance state. This model consists of a 100pF capaci-
tor charged to the ESD voltage of interest that is then
discharged into the device through a 1.5k I resistor.
IEC 61000-4-2
The IEC 6100-4-2 standard covers ESD testing and per-
formance of finished equipment. However, it does not
specifically refer to integrated circuits. The device assists
in designing equipment to meet IEC 61000-4-2 without
the need for additional ESD protection components.
The major difference between tests done using the HBM
and IEC 61000-4-2 is higher peak current in IEC 61000-
4-2 because series resistance is lower in the IEC 61000-
4-2 model. Hence, the ESD withstand voltage measured
to IEC 61000-4-2 is generally lower than that measured
using the HBM. Figure 4 shows the IEC 61000-4-2 model,
and Figure 5 shows the current waveform for the IEC
61000-4-2 ESD Contact Discharge test.
