3 Description
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.
