USB Filter 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 (TSOP–6, Case 318G) reducing PCB space and cost.

Features:

• Provides USB Line Termination, Filtering and ESD Protection

• Single IC Offers Cost Savings by Replacing 3 Resistors, 2 Capacitors, and 5 TVs diodes

• Bi–directional EMI Filtering Prevents Noise from Entering/Leaving the System

• IEC61000–4–2 ESD Protection for USB Port

• Flexible Pull–down or Pull–up Line Termination to Meet USB 1.1 Low Speed and High Speed Specification

• ESD Ratings: Machine Model = C

Human Body Model = 3B

Benefits:

• TSOP–6 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
