USB Downstream Port Terminator PACUSB-D1/D2/D3 Features • A low-capacitance USB downstream port terminator, EMI filter, and transient over-voltage (ESD) protector in a single surface-mounted package ESD protection to +20kV contact discharge, per MIL-STD-883D, Method 3015 ESD protection to +15kV contact discharge, per IEC 61000-4-2 International Standard Compact SOT23-5 and SC70-5 package options save board space and lower manufacturing costs compared to discrete solutions Capacitors matched to a precision exceeding the USB specification Pin-compatible with ST Microelectronics USBDFxxW5 USB Downstream Port Terminator Lead-free versions available Product Description The PACUS B-D1/D2/D3 is a single-channel USB downstream-port te rmination n etwork. It integrate s EMI/RFI filter components R1 a nd C1, as recommended by th e US B spe cification as well a s the re quired 15kW p ull-down resistors (R2) t o G ND. In addition, P ACUSB-D1/D2/D3 provides a very high level of protection for sensitive electronic components that ma y b e su bjected t o ele ctrostatic di scharge (ESD). The devi ce pins will safel y dissipate ESD strikes of +15kV, ex ceeding t he maximum requirements of the IEC 610 00-4-2 internatio nal standard. Using the MI L-STD-883D (Method 3015) specification for Human B ody Model (HBM) ES D, all pins are protected from contact discharges to +20kV. There a re th ree options f or the value of the seri es resistor R1: 15 Ω, 22 Ω, and 33 Ω. T his s eries resistance, plus the USB driver output resi stance, must b e close t o t he USB cabl e’s characteristic impedance of 45Ω (e ach side) to minimize transmission line reflections. The PACUS B-D1/D2/D3 i s man ufactured in a 5-pin SC70 or a 5-pin SOT23 package and is available with optional lead-free finishing.. • • • • • • Applications • • • • • ESD protection and termination of USB downstream ports Desktop PCs Notebooks Set-top boxes USB hubs ©2010 SCILLC.
