DESCRIPTION
The SN65220 is a single transient voltage suppressor
designed to provide electrical noise transient protection to
universal serial bus (USB) 1.1 ports. Note that the input
capacitance of the device makes it unsuitable for
high-speed USB 2.0 applications.
Any cabled I/O can be subjected to electrical noise
transients from various sources. These noise transients
can cause damage to the USB transceiver and/or the USB
ASIC if they are of sufficient magnitude and duration.
USB ports are typically implemented in 3-V or 5-V digital
CMOS with limited ESD protection. The SN65220 can
significantly increase the port ESD protection level and
reduce the risk of damage to the circuits of the USB port.
The IEC1000-4-2 ESD performance of the SN65220 is
measured at the system level. Therefore, system design
impacts the results of these tests. A high compliance level
may be attained with proper board design and layout.
