SP3003-02XTG Datasheet, PDF (1/1 Pages) Littelfuse – Silicon Protection Arrays

Silicon Protection Arrays
Application Guide
USB2.0
Considerations:
● Each port can operate up to 480Mbps
→ The high data rate requires a low capacitance device to preserve signal integrity
● Requires 2 channels of data line protection per port (i.e. D+/D-)
→ A 4 channel device can be useful if protecting a USB stack of 2 ports to make the
ESD footprint as small as possible
→ V_BUS can be protected by connecting it to the V_CC pin on the diode array or by using a separate single channel
device as previously shown (i.e. SP1003)
