7.1 Overview
The TPD13S523 device is a single-chip ESD solution for the HDMI transmitter port. By providing system-level
ESD protection for a full HDMI port, the TPD13S523 can protect the core IC from ESD strikes and absorb the
associated energy.
While providing the ESD protection, the TPD13S523 adds little-to-no signal distortion to the high-speed
differential signals. In addition, the monolithic integrated circuit technology ensures that there is excellent
matching between the two-signal pair of the differential line.
The TPD13S523 also provides an on-chip regulator with current output ratings of 55 mA at pin 38. This current
enables HDMI receiver detection even when the receiver device is powered off.

7.3 Feature Description
7.3.1 IEC 61000-4-2 Protection
The connector-facing I/O pins can withstand ESD events up to ±12-kV contact and ±14-kV air. An ESD clamp
diverts the current to ground.
7.3.2 Single-Chip ESD Solution
The TPD13S523 provides a complete ESD protection scheme for an HDMI 1.4 compliant port. No additional
components are required for ESD protection and current-limiting besides this device.
