IP4786CZ32Y

The Nexperia USA Inc. IP4786CZ32Y is a specialized interface integrated circuit designed to protect High-Definition Multimedia Interface (HDMI) transmitter host interfaces. It provides comprehensive protection including 5V overcurrent/overvoltage protection, Display Data Channel (DDC) buffering and decoupling, hot plug detect, backdrive protection, Consumer Electronic Control (CEC) buffering and decoupling, and ±12 kV contact ElectroStatic Discharge (ESD) protection for all I/Os, exceeding the IEC 61000-4-2 level 4 standard.

This IC incorporates Transmission Line Clamping (TLC) technology on the high-speed Transition Minimized Differential Signaling (TMDS) lines to simplify routing and reduce impedance discontinuities. The enhanced 60 mA overcurrent/overvoltage linear regulator ensures HDMI-compliant 5V output voltage levels even with up to 6.5V inputs. The DDC lines utilize a new buffering concept that decouples internal and external capacitive loads, supporting standard CMOS or LVTTL I/O cells down to 1.8V. This buffering also redrives DDC and CEC signals, enabling the use of longer or cheaper HDMI cables with higher capacitance. The integrated hot plug detect module simplifies HDMI transmitter control of the hot plug signal.

Packaged in a 32-HVQFN (5x5) surface-mount package, the IP4786CZ32Y is suitable for applications such as DVD players, HD devices, and set-top boxes. It operates with supply voltages of 3.3V and 5V and is RoHS3 Compliant.
