The TPD13S523 device is a single-chip integrated IEC 61000-4-2 ESD protection solution
for HDMI 1.4 or HDMI 1.3 interfaces. This device offers 13 channels of TVS diodes with flow-through
pin mapping that matches HDMI connector high-speed lines. While providing ESD protection, the
TPD13S523 adds little to no additional distortion to the high-speed differential signals. The
monolithic integrated circuit technology ensures that there is excellent matching between the
two-signal pair of the differential line (< 0.05-pF differential matching between TMDS lines).
This offers an advantage over discrete ESD solutions where variations between two different ESD
protection circuits may significantly degrade the differential signal quality.
The TPD13S523 incorporates an on-chip current limited load switch that is compliant with
HDMI 5-V out electrical specifications. The short-circuit protection at 5V_OUT ensures that the
device is not damaged in case there is an accidental short to GND. The load switch also
incorporates a reverse-current blocking feature which ensures that the HDMI driver side is not
erroneously turned on when two HDMI drivers are connected together.
Typical applications for the TPD13S523 include set top boxes (STB), e-books, tablets,
smart phones, and camcorders.
