    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
    2×2 mm QFN package.
