NUF2221W1
USB Upstream Terminator
with ESD Protection
This device is designed for applications requiring Line
Termination, EMI Filtering and ESD Protection. It is intended for
use in upstream USB ports, Cellular phones, Wireless equipment and
computer applications. This device offers an integrated solution in a
small package (SC−88/SOT−363) reducing PCB space and cost.
Features
• Provides USB Line Termination, Filtering and ESD Protection
• Single IC Offers Cost Savings
• Bi−directional EMI Filtering Prevents Noise from Entering/Leaving
the System
• Compliance with IEC61000−4−2 (Level 4)
25 kV (Contact)
30 kV (Air)
• Flexible Pull−up Line Termination to Meet USB 1.1 Low Speed and
High Speed Specification
• ESD Ratings: Machine Model = C
ESD Ratings: Human Body Model = 3B
• This is a Pb−Free Device
Benefits
• SC−88 Package Minimizes PCB Space
• Integrated Circuit Increases System Reliability versus Discrete
Component Implementation
• TVS Devices Provide ESD Protection That is Better than a Discrete
Implementation because the Small IC minimizes Parasitic
Inductances
Typical Applications
• USB Hubs
• Computer Peripherals Using USB
