a 1μF capacitor must be connected from V BUS to GND
as close to the device as possible. The ESD structures
withstand high ESD in all states — normal operation,
shutdown, and powered down. ESD protection can be
tested in various ways. The ID_IN input and V BUS are
characterized for protection to the following limits:

CURRENT WAVEFORM
Figure 2. Human Body Current Waveform
OFFVBUS
Connect OFFVBUS to GND to disable V BUS and the
charge pump (Table 4). For normal V BUS operation,
connect OFFVBUS to V L . When OFFVBUS = GND, V BUS
impedance is between 40k ? to 100k ? as defined in On-
the-Go Supplement: USB 2.0, Revision 1.0.
SHDN
The MAX3355E shutdown mode reduces supply current
to less than 1μA. To enter shutdown mode, connect
SHDN to GND. Shutdown mode disables the charge
pump and comparators (Table 4). While in shutdown
mode, the STATUS1 output defaults to logic 0 and STA-
TUS2 indicates V BUS . During shutdown, if V BUS is exter-
nally driven above V TH, SHDN (defined in the Comparators
section), the MAX3355E sinks current from V CC .

ESD performance depends on a variety of conditions.

test setup, test methodology, and test results.
Human Body Model
Figure 1 shows the Human Body Model and Figure 2
shows the current waveform it generates when dis-
charged into a low impedance. This model consists of a
100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the test device through a
1.5k ? resistor.
IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and
performance of finished equipment. It does not specifi-
cally refer to integrated circuits. The MAX3355E helps
the user design equipment that meets Level 4 of IEC
1000-4-2, without the need for additional ESD-protec-
tion components. The major difference between tests
done using the Human Body Model and IEC 1000-4-2
is a higher peak current in IEC 1000-4-2. This occurs
because series resistance is lower in the IEC 1000-4-2
model. Hence, the ESD withstand voltage measured to
