3.1

ESD & Transient Performance

APPLICATION NOTE: Depending on the level of ESD protection required by the application, external protection

devices may be required. The datasheet ESD levels were reached using external devices

and standard USB-A connectors; refer to the EVB schematic and reference design for

details.

Note 3.3

Operational Classification B indicates that during and immediately after an ESD event,

anomalous behavior may occur; however, it is non-damaging and the device is self-

recovering. All IEC testing is performed using an SMSC evaluation board.

Note 3.4

Operational Classification A indicates that during and immediately after an ESD event no

anomalous behavior will occur. All IEC testing is performed using an SMSC evaluation

board.

3.1.1

Human Body Model (HBM) Performance

HBM testing verifies the ability to withstand ESD strikes like those that occur during handling and

manufacturing and is done without power applied to the IC. To pass the test, the device must have no

change in operation or performance due to the event.

3.1.2

Charged Device Model (CDM) Performance

CDM testing verifies the ability to withstand ESD strikes like those that occur during handling and

assembly with pick and place style machinery and is done without power applied to the IC. To pass

the test, the device must have no change in operation or performance due to the event.

3.1.3

IEC61000-4-2 Performance

The IEC61000-4-2 ESD specification is an international standard that addresses system-level immunity

to ESD strikes while the end equipment is operational. These tests are performed while the device is

powered.
