DESCRIPTION

−10

−5

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.

Voltage − V

NOTE A: Typical current versus voltage curve was derived

using the IEC 1.2/50-µs surge waveform.

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.

EQUIVALENT SCHEMATIC DIAGRAM

A or C

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.

GND

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.

B or D

(One Suppressor Shown)

NOTE All GND terminals should be connected to ground.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments

semiconductor products and disclaimers thereto appears at the end of this data sheet.
