Dual USB 2.0 Integrated ESD Protection
FEATURES * * * * ESD IEC 61000-4-2 level 4, 8kV contact discharge compliant protection Four ultra-low input capacitance (1 pF typ.) ESD rail-to-rail protection diodes Low voltage clamping due to integrated Zener diode Small 6 lead SO6 (SOT457) package
IP4220CZ6
APPLICATIONS General-purpose downstream ESD protection high frequency analog signals and high-speed serial data transmission for ports inside: * * * * * * Cellular and PCS mobile handsets PC-/Notebook USB2.0/IEEE1394 ports DVI interfaces Cordless telephones Wireless data (WAN/LAN) systems PDAs 1 DESCRIPTION The IP4220CZ6 is designed to protect I/Os being sensitive concerning capacitive load, such as USB 2.0, Ethernet, DVI etc. from destruction by Electro Static Discharges (ESD). Therefore, the IP4220CZ6 incorporates four pairs of ultra-low capacity rail-to-rail diodes plus an additional Zener diode to provide protection to downstream signal and supply components from Electrostatic Discharge (ESD) voltages as high as 8 kV contact discharge. Due to the rail-to-rail diodes being connected to the Zener diode, the protection is working independent form the availability of a supply voltage. The IP4220CZ6 is fabricated using thin film-onsilicon technology and integrates 4 ultra-low capacity rail-to-rail ESD protection diodes in a miniature 6-lead SOT457 package. 6
