Upstream USB Port Terminator with ESD Suppression & EMI Filtering
SPUSB1 Series NEW
The Littelfuse SPUSB1 Series is a multifunctional USB port protection network designed to provide ESD protection, EMI/RFI filtering and line termination for a single USB 1.1 port. The SPUSB1 can replace a minimum of ten typically larger “discrete” devices resulting in inventory and placement cost savings.
The SPUSB1 Series combines Transient Voltage Suppression (TVS) avalanche diodes, EMI/RFI filtering components (R1 and C1), and a 1.5kΩ termination resistor (R2). The filtering components are included to satisfy recommendations in the USB 1.1 specification, and the 1.5kΩ resistor (R2) is included as a pull-up resistor to VBUS.
