D+, D-, and VBCOMP possess extra protection against
static electricity to protect the devices up to ±15kV. The
ESD structures withstand high ESD in all operating
modes: normal operation, suspend mode, and pow-
ered down. VBCOMP and V
capacitors connected to ground as close to the pins as

ESD performance depends on a variety of conditions.

Figure 18 shows the Human Body Model, and Figure 19
shows the current waveform generated when dis-
charged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of inter-
est, which then discharges into the test device through
a 1.5kΩ resistor.
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. It does not specifi-
cally refer to integrated circuits. The major difference
between tests done using the Human Body Model and
IEC 61000-4-2 is a higher peak current in IEC 61000-4-
2, due to lower series resistance. Hence, the ESD with-
stand voltage measured to IEC 61000-4-2 generally is
lower than that measured using the Human Body
Model. Figure 20 shows the IEC 61000-4-2 model. The
Contact Discharge method connects the probe to the
device before the probe is charged. The Air-Gap
Discharge test involves approaching the device with a
charged probe.
The MAX3420E withstands V
on the USB connector side of the 33Ω series resistors.
