DVI and HDMI interface ESD protection, DDC/CEC buffering, hot plug handling and backdrive protection
The IP4787CZ32 is designed to protect High-Definition Multimedia Interface (HDMI) receiver interfaces. It includes HDMI 5 V power management, Display Data Channel (DDC) buffering and decoupling, hot plug drive, backdrive protection, Consumer Electronic Control (CEC) buffering and decoupling, and ±12 kV contact ElectroStatic Discharge (ESD) protection for all external I/Os, exceeding the IEC 61000-4-2, level 4 standard.
The IP4787CZ32 incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition-Minimized Differential Signaling (TMDS) lines to simplify routing and help reduce impedance discontinuities. All TMDS lines are protected by an impedance-matched diode configuration that minimizes impedance discontinuities caused by typical shunt diodes.
The 5 V power management enables host access to the [Extended Display Identification Data (EDID)] memory even if no HDMI plug is connected. The overall load to the 5 V line is according to the HDMI requirements.
The DDC lines use a buffering concept which decouples the internal capacitive load from the external capacitive load for use with standard Complementary Metal Oxide Semiconductor (CMOS) or Low Voltage Transistor-Transistor Logic (LVTTL) I/O cells down to 1.2 V. This buffering also redrives the DDC and CEC signals, allowing the use of longer or cheaper HDMI cables with a higher capacitance. The internal hot plug drive module simplifies the application of the HDMI receiver to control the hot plug signal.
All lines provide appropriate integrated pull-ups and pull-downs for HDMI compliance and backdrive protection to guarantee that HDMI interface signals are not pulled down if the system is powered down or enters Standby mode. Only a single external capacitor is required for operation.

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.
