The ISL78365 laser diode driver from Intersil suits automotive head-up display (HUD) systems. The highly integrated device pulses four high intensity lasers to 750 mA for projecting full-HD color video onto the windshield at nearly twice the current of competitive solutions. It is the industry’s only laser driver with a fourth channel for supporting a wide variety of laser diode configurations, allowing system designers to achieve the desired brightness and sharp, rich colors with high contrast.
The quad-channel driver is a complete solution for driving lasers in the scanned-MEMS laser projection systems being deployed in next generation autos. The device’s higher current and faster switching speed enables HUDs with high resolution, high color-depth and high frame-rate projections. It provides sub-1.5 ns rise and fall times for faster switching speeds than competitive devices, resulting in high-frame rate, HD color video. The device also offers 10-bit color and 10-bit scale resolution to support a wide variety of contrast levels for each driver channel. And its flexible synchronous parallel video interface supports pixel rates up to 150 MHz or 1,900 pixels per line. The driver offers three power saving modes for improved efficiency and reduced power dissipation to meet system thermal requirements.
