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.
