Laser Diode Driver for Automotive Heads-Up Displays

Intersil announced the ISL78365 laser diode driver for automotive heads-up display (HUD) systems. The highly integrated device pulses four high intensity lasers up to 750mA for projecting full-HD color video onto the windshield at nearly twice the current of competitive solutions. The ISL78365's higher current and faster switching speed enables HUDs with high resolution, high color-depth and high frame-rate projections.

Laser HUDs are the latest innovation in advanced driver assistance systems (ADAS). A vehicle's HUD keeps drivers focused on the road, safely providing speed, warning signals and other vital vehicle and navigation information on the windshield directly in the driver's line of sight. The new generation of augmented reality laser HUDs offer near-zero latency and a wide field of view. They overlay additional real-time information such as traffic signs and a planned turning lane, virtually painting arrows and lines on the road ahead to make navigation directions obvious and easy to follow.

The quad-channel ISL78365 is a complete solution for driving lasers in the scanned-MEMS laser projection systems being deployed in next generation autos. 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 ISL78365 provides sub-1.5ns rise and fall times for faster switching speed 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 150MHz or 1900 pixels per line.

The quad-channel ISL78365 laser diode driver is available now in a 6mm x 6mm 40-lead WFQFN package and is priced at $9.82 USD in 1k quantities.
