RGB laser driver for head-up displays outshines LED-driven pico projectors

January 23, 2013 // By Christoph Hammerschmidt
Maxim Integrated Products is sampling the MAX3601, a highly integrated, 8-bit RGB laser driver for pico laser projectors in automobiles. With its small size it enables sharp, pixel-perfect heads-up displays (HUD) in cars. Compared to existing solutions, the MAX3601 excels through brighter light and lower cost.

The MAX3601 drives three RGB lasers to provide a brighter light without compromising the low power. The high intensity of the lasers project brighter, more vivid images onto the HUD to alert the driver while enhancing safety. In addition, its high integration means longer battery life, less heat build-up, and a smaller module size.

Since the three laser LED drivers are combined into one single IC, the high integration of the device helps to minimize the PCB area in the cramped space behind the dashboard. No separate optics is required. With its low bias power of only 80mW and less than 1W total module power, the chip achieves excellent power efficiency and helps designers to keep heat dissipation and thermal sinking low.

“One of the key trends for automotive displays is higher resolution, “said Richard Robinson, Director of Automotive Analysis at Strategy Analytics. “Sharper imagery in head-up displays is critical for clarity, safety, and driver assistance applications.”

The chip is available in 3 mm x 3.5 mm, 42-bump WLP and 5 mm x 5 mm, 40-pin TQFN packages. It is specified over the -40 °C to +105 °C temperature range.
