IEC 1000-4-2
The IEC 1000-4-2 standard covers ESD testing and per-
formance of finished equipment; it does not specifically
refer to integrated circuits. The MAX3344E/MAX3345E
help the user design equipment that meets level 4 of IEC
1000-4-2, without the need for additional ESD-protection
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, because series resistance is
lower in the IEC 1000-4-2 model. Hence, the ESD with-
stand voltage measured to IEC 1000-4-2 is generally
lower than that measured using the Human Body Model.
Figure 1c shows the IEC 1000-4-2 model.
The Air-Gap Discharge Method involves approaching
the device with a charged probe. The Contact
Discharge Method connects the probe to the device
before the probe is energized.
Machine Model
The Machine Model for ESD tests all pins using a 200pF
storage capacitor and zero discharge resistance. Its
objective is to emulate the stress caused by contact that
occurs with handling and assembly during manufactur-
ing. All pins require this protection during manufactur-
ing. Therefore, after PC board assembly, the Machine
Model is less relevant to I/O ports.
Applications Information
External Components
External Resistors
Two external 23.7
±1% to 27.4
±1%, 1/2W resistors
are required for USB connection. Place the resistors
in between the MAX3344E/MAX3345E and the USB
connector on the D+ and D- lines (see the
Typical
Operating Circuit
).
External Capacitors
Use three external capacitors for proper operation. Use
a 0.1μF ceramic for decoupling V
L
, a 1μF ceramic for
decoupling V
CC
, and a 1.0μF (min) ceramic or plastic
filter capacitor on VTRM. Return all capacitors to GND.
