USB Downstream Port Terminator with VBUS ESD Protection
PRODUCT DESCRIPTION |
|||||||||
|
The PACUSBVB-D1/D2/D3 is a single-channel USB downstream-port termination network. It integrates EMI/RFI filter components R1 and C1, as recommended by the USB specification as well as the required 15kΩ pull-down resistors (R2) to GND. In addition, PACUSBVB-D1/D2/D3 provides a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The device pins will safely dissipate ESD strikes of ±15kV, exceeding the maximum requirements of the IEC 61000-4-2 international standard. Using the MIL-STD-883D (Method 3015) specification for Human Body Model (HBM) ESD, all pins are protected from contact discharges to ±20kV. The PACUSBVB-D1/D2/D3 also features a fifth zener diode (cathode at pin 5) which provides ESD protection for the USB VBUS line. There are three options for the value of the series resistor R1: 15Ω, 33Ω, and 22Ω. This series resistance, plus the USB driver output resistance, must be close to the USB cable's characteristic impedance of 45Ω (each side) to minimize transmission line reflections. The PACUSBVB-D1/D2/D3 is housed in a 6-pin SOT23 package and is available with optional lead-free finishing. Note: Some of the devices listed here have suggested replacements available.
