TPD13S523PWR

13通道ESD保护解决方案与限流负载开关的HDMI端口 13 Channel ESD Protection Solution with Current-Limit Load Switch for HDMI Port

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.
