Description
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
