IP4223CZ6
Dual USB 2.0 integrated ESD protection
1. Product profile
1.1 General descriptionThe IP4223CZ6 is designed to protect I/O lines sensitive to capacitive load, such as
USB 2.0, ethernet, Digital Video Interface (DVI) and so on, from damage due to
ElectroStatic Discharge (ESD). It incorporates four pairs of ultra low capacitance rail-to-rail
ESD protection diodes plus a Zener diode to provide protection to signal and supply
components from ESD voltages up to 8 kV contact discharge. Protection is supply
voltage independent due to the rail-to-rail diodes being connected to the Zener diode.
The device is encapsulated in a small 6-lead SOT457 (SC-74) Surface-Mounted
Device (SMD) plastic package.
1.2 Features and benefits Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen
and antimony (Dark Green compliant) ESD protection up to 8 kV contact discharge; IEC 61000-4-2, level 4 compliant Four pairs of ultra low input capacitance (C(I/O-GND)= 1.5 pF) ESD rail-to-rail protection
diodes Low voltage clamping due to integrated Zener diode Small 6-lead TSOP6 (SOT457) SMD package
1.3 Applications General-purpose downstream ESD protection for high-frequency analog signal ports
and high-speed serial data transmission ports in: Cellular phone and Personal Communication System (PCS) mobile handsets PC/notebook USB 2.0/IEEE1394 ports DVI Cordless telephones Wireless data (WAN/LAN) systems Mobile Internet Devices (MID) Portable Media Players (PMP) High-Definition Multimedia Interface (HDMI)
