ESD Protection
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 VCC require 1F ceramic
capacitors connected to ground as close to the pins as
possible. D+, D-, and VBCOMP provide protection to
the following limits:
±15kV using the Human Body Model
±8kV using the Contact Discharge method specified
in IEC 61000-4-2
±12kV using the IEC 61000-4-2 Air Gap Method
ESD Test Conditions
ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, test methodology, and test results.
Human Body Model
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 1.5k
Ω resistor.
IEC 61000-4-2
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.
Short-Circuit Protection
The MAX3420E withstands VBUS shorts to D+ and D-
on the USB connector side of the 33
Ω series resistors.
