8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The TPD13S523 provides IEC 61000-4-2 Level 4 Contact ESD protection for an HDMI 1.4 transmitter port. An

integrated current limit switch ensures compliance with the HDMI 5-V power supply requirements. This section

presents a simplified discussion of the design process for this protection device.

8.2 Typical Application

A typical application schematic for an HDMI 1.4 transmitter port protected by the TPD13S523 is shown in

Figure 11. The eight TMDS lines and five control lines are connected to their respective pins for ESD protection.

The 5-V power path is connected through the 55-mA current limit switch.
