Technical content

Features

  • One upstream USB port terminator, EMI filter and transient overvoltage protector in a single surface- mount package
  • Compact SC70 or SOT23 package saves board space and lowers manufacturing costs compared to discrete solutions
  • ESD protection to ±30kV contact discharge per MIL-STD-883D, method 3015
  • ESD protection to ±15kV contact discharge per IEC 61000-4-2 international standard
  • Lead-free version available

Applications

  • ESD protection and termination of USB port
  • All USB peripherals (PC printers, scanners, zip drives, etc.)
  • PDAs / handheld PCs
  • Digital cameras
  • Wireless Handets
  • MP3 Players
  • Cable Modems Product Description The PACUSB-U1, PACUSB-U2, and PACUSB-U3 are single-channel USB upstream-port termination net- works. The PACUSB-U1/U2/U3 integr ate EMI/RFI filter com- ponents R1 and C1, as recommended by the USB specification. Because these are upstream USB devices, they are terminated with a single 1.5kΩ pull-up resistor to V 3.3 (R2). There are three options for the value of the series resistor R1:
  • For PACUSB-U1, R1=15 Ω
  • For PACUSB-U2, R1=33 Ω
  • For PACUSB-U3, R1=22 Ω This series resistance plus the USB driver output resis- tance must be close to th e USB cable’s characteristic impedance of 45 Ω (90 Ω balanced) to minimize trans- mission line reflections. In addition, these parts provide a very high level of pro- tection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The input and output pins are designed and characterized to dis- sipate ESD strikes of ±15kV safely, a level well beyond the maximum requirements of the IEC 61000-4-2 inter- national standard. Using the MIL-STD-883D (Method 3015) specification for Human Body Model (HBM) ESD, all pins are pro- tected for contact discharges to greater than ±30kV. The PACUSB-U1/U2/U3 is housed in either a 6-pin SC70 or 6-pin SOT23 package and is available with optional lead-free finishing.

Clamping voltage is measured at the opposite side of the EMI filter to the ESD pin (i.e., if ESD is applied to pin 1, then clamping voltage is measured at pin 6). Unused pins are open.
