Overvoltage-Protection Controllers with
Status FLAG
Since January 1996, all equipment manufactured and/or
sold in the European community has been required to
meet the stringent IEC 61000-4-2 specification. The IEC
61000-4-2 standard covers ESD testing and perfor-
mance of finished equipment; it does not specifically
refer to integrated circuits. The MAX4838A/MAX4840A/
MAX4842A help users design equipment that meets
Level 3 of IEC 61000-4-2, without additional ESD-protec-
tion components.
The main difference between tests done using the
Human Body Model 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 ESD test model (Figure 10),

the ESD-withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 11 shows the current waveform for
the ±8kV IEC 61000-4-2 Level 4 ESD Contact
Discharge test. The Air-Gap test involves approaching
the device with a charger probe. The Contact
Discharge method connects the probe to the device
before the probe is energized.
