Description

The TPD12S521 is a single-chip electro-static discharge (ESD) circuit protection device for the high-definition multimedia interface (HDMI) transmitter port. While providing ESD protection with transient voltage suppression (TVS) diodes, the TVS protection adds little or no additional glitch in the high-speed differential signals. The high-speed transition minimized differential signaling (TMDS) ESD protection lines add only 0.8-pF capacitance.

The low-speed control lines offer voltage-level shifting to eliminate the need for an external voltage level-shifter IC. The control line TVS diodes add 3.5-pF capacitance to the control lines. The 38-pin DBT package offers a seamless layout routing option to eliminate the routing glitch for the differential signal pairs. The DBT package pitch (0.5 mm) matches with the HDMI connector pitch. In addition, the pin mapping follows the same order as the HDMI connector pin mapping. The TPD12S521 provides an on-chip current limiting switch with output ratings of 55 mA at pin 38. This enables HDMI receiver detection even when the receiver device is powered off.
