IP4309CX9 HDMI octal channel low capacitive high-performance ESD protection Rev. 1 10 March 2011 Product data sheet 1. Product profile 1.1 General description The IP4309CX9 is a 8-channel low capacitance ElectroStatic Discharge (ESD) protection device, providing protection to downstream components from ESD voltages up to 15 kV contact discharge and higher than 15 kV air discharge, far exceeding IEC 61000-4-2, level 4. The device is optimized for the protection of high-speed interfaces such as High-Definition Multimedia Interface (HDMI), Digital Video Interface (DVI) and other interfaces requiring very low capacitance ESD protection. In order to prevent any current backdrive into the adjacent channel, all eight ESD protection channels are electrically separated and share only the same ground connections. The IP4309CX9 is fabricated using monolithic silicon technology in a single Wafer Level Chip-Size Package (WLCSP). These features make IP4309CX9 ideal for use in applications requiring component miniaturization, such as mobile phone handsets. 1.2 Features and benefits Pb-free, Restriction of Hazardous Substances (RoHS) compliant and free of halogen and antimony (dark green compliant) 8 ultra low input capacitance rail-to-rail ESD protection diodes with C =1.3 pF I/O R =0.45 dyn Downstream ESD protection up to 15 kV (contact), exceeding IEC 61000-4-2, level 4 3 3 pin WLCSP with 0.4 mm pitch 1.3 Applications High-speed interface ESD protection such as HDMI, DVI and USB etc. Interfaces with special requirements on low capacitive ESD protection Interfaces requiring separation of the positive clamping voltage / current pathIP4309CX9 NXP Semiconductors HDMI octal channel low capacitive high-performance ESD protection 2.
