INTERSIL Introduces the Industry's Highest Performance Laser Diode Driver for Automotive Head Up Dis

California, Milpitas - June 1, 2016 - INTERSIL Corporation (NASDAQ: ISIL), a leading supplier of innovative power management and precision simulation solutions, today announced the launch of isl78365, a laser diode driver for automotive head up display (HUD) system. This highly integrated device can drive the maximum current of up to 750ma of four high-intensity laser diodes to project full HD color video onto the windshield. Its current is nearly twice that of the competitor's solution. The higher current and faster switching speed of isl78365 enable HUD to achieve high resolution, high color depth and high frame rate projection.

Laser HUD is the latest innovation in the field of advanced driving assistance system (ADAS). The vehicle's HUD system projects speed, warning signals and other key vehicle and navigation information onto the windshield within the driver's line of sight, which helps the driver to focus on the road conditions and ensure driving safety. The new generation of augmented reality laser HUD provides near zero delay and wide field of vision. They can also overlay more real-time information, such as traffic signs and expected turning lanes, and virtually mark arrows and markings on the road ahead, so that the navigation direction is clear and easy to follow.

The four channel isl78365 is a complete solution for driving the laser in the scanning MEMS laser projection system used in the next generation of vehicles. It is the only four channel laser driver in the industry, which can support a wide range of laser diode configurations, enabling system design engineers to achieve the required intensity and clear and rich colors with high contrast. Isl78365 provides rise and fall times of less than 1.5 nanoseconds, and its switching speed is faster than that of competitor devices, so as to realize high frame rate HD color video. In addition, the device also provides 10 bit color and 10 bit scaling resolution to support the wide contrast level required by each driver channel. At the same time, its flexible synchronous parallel video interface supports a maximum 150MHz pixel rate or 1900 pixels per line.

The dynamic power management function of isl78365 can optimize the laser diode power supply and provide three power saving modes to improve efficiency and reduce power dissipation, so as to meet the heat dissipation requirements of the system. The programmable polyphase zeroing (RTZ) function can reduce speckle, and the wettable side QFN package of the device can be easily integrated into a compact laser projection HUD system.

Philip Chesley, senior vice president of precision products of INTERSIL, said: "The HUD solution provided by isl78365 to automakers is almost perfect in terms of resolution, color depth and frame rate. Our feature rich laser diode driver minimizes system size and complexity, while providing significantly higher performance than competitors."
