PI3AUX221ZTAEX

PI3AUX221 is an interface chip between the discrete Graphics Processing Unit (GPU) and the Display Port (DP) connector. The device is ideal for applications that require support of Dual-Mode Display Port. It integrates the support function for Display Data Channel (DDC) in HDMI mode and includes the functions of level translation, mux function, over-voltage protection, back-drive protection and inversion of Hot Plug Detect (HPD). The level translation function allows a wide range of voltages between 1V to 5V. The device eliminates the requirement of many discrete components, and it is available in a space-saving 12-pin ultra-thin 0.65mm high 2x2 mm QFN package.

Applications
