TPD13S523EVM
The TPD13S523 is a single-chip integrated ESD protection solution for the HDMI 1.4 or HDMI 1.3
interface. This device offers 13 channel ESD clamp circuits with flow-through pin mapping to match the
HDMI connector high-speed lines. While providing ESD protection, TPD13S523 adds little or no additional
distortion to the high-speed differential signals. The monolithic integrated circuit technology ensures that
there is matching between the two-signal pair of the differential lines (<0.05pF differential matching
between TMDS lines). This technology is an advantage over discrete ESD clamp solutions where
variations between two different ESD clamps may significantly degrade the differential signal quality.

The TPD13S523 comes with an on-chip current limited load switch that is HDMI 1.4 compliant. The 55mA
current at the 5V_OUT pin enables HDMI receiver detection even when the receiver device is powered off.
The short circuit protection ensures that the device is not damaged in case there is an accidental short to
GND.
