HDMI interface with load switch and logic level translator

April 24, 2014 // By Graham Prophet
China-based SG Micro has introduced a new HDMI interface IC with load switch and logic level translator. The SGM4561 provides the load switch and signal level shifting needed for an HDMI interface.

The part meets all type approval requirements of logical level shifting for the HDMI interface and contains a 5.0V load switch to protect hot-insertion of an HDMI connection. The load switch can support 200 mA of load current; the internal level translators allow controllers operating with supplies as low as 1.6V to translate 1.8V or 2.8V or 3.3V logical level to the 5.0V logical level used by the HDMI interface. The SGM4561 has a low operating current of typically 100 μA.

The SGM4561 is available in the Green MSOP-10 package. It operates over an ambient temperature range of -40℃ to +85℃. Other features include; 5.0V to 5.5V input voltage range for load switch; 1.6V to 5.5V Controller side logical level voltage range; shutdown current of 1 μA.
