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.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
