ESD performance depends on a variety of conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Figure 22 shows the Human Body Model and Figure 23
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
1.5kΩ 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 MAX3301E/
MAX3302E helps the user design equipment that meets
level 3 of IEC 61000-4-2, without the need for additional
ESD-protection components. 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 the fact that 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 Human Body Model. Figure 24
shows the IEC 61000-4-2 model. The Air-Gap Discharge

Set to 0 to enable shutdown mode. Set to 1 for normal operation. Only the I
interface remains active in shutdown.
Set to 0 to set INT and OE/INT as open-drain outputs. Set to 1 to set INT and
OE/INT as push-pull outputs.

test involves approaching the device with a charged
probe. The contact discharge method connects the
probe to the device before the probe is energized.
Figure 25 shows the IEC 61000-4-2 current waveform.
The MAX3301E/MAX3302E high operating frequency
makes proper layout important to ensure stability and
maintain the output voltage under all loads. For best
performance, minimize the distance between the
bypass capacitors and the MAX3301E/MAX3302E. Use
symmetric trace geometry from D+ and D- to the USB
connector.
