IP4791CZ12: HDMI ESD protection, level shifter and backdrive protection
The IP4791CZ12 is designed to protect mobile High-Definition Multimedia Interface (HDMI) transmitter interfaces. It includes level shifting for the Data Display Channel (DDC), Consumer Electronic Control (CEC), hot plug signal and backdrive protection. In addition, all signals are protected by high-level ElectroStatic Discharge (ESD) protection diodes.
The level shifting function is required to protect the I/Os against overvoltages when the transmitter operates at a supply voltage lower than the external devices. The IP4791CZ12 contains active buffers to provide the level shifting function, hot plug detect input and the CEC pull-up current source.
The ESD protection diodes provide protection from ESD voltages up to ±8 kV, according to IEC 61000-4-2, level 4.
