... The HDMI contains various signals which can partly supply current into an HDMI device that is powered down. Typically, the DDC lines and the CEC signals can force 5 V into the switched-off device. The IP4778CZ38 ensures that at power-down, the critical signals are blocked to prevent any damage to the HDMI sink and HDMI source. Fig 13. Backdrive protection ...
