LED matrix manager IC lights up adaptive automotive headlights markett

The TPS92661-Q1 is the first fully integrated high-brightness LED matrix manager IC that enables automobile manufacturers to create innovative LED headlamps that vary beam patterns and intensity dynamically for optimum roadway illumination and enhanced driver safety. Until now, headlamp beam forming and directional control in an adaptive headlamp design required considerable board space to house bulky discrete circuits, including multiple transistors, gate drivers, and glue logic. A single TPS92661-Q1 replaces this complex design, reducing board space by 73%, and enables a headlamp system that is completely solid state with no moving parts that can wear out, such as motors or actuators.

Featured in premium vehicles today and proliferating into mainstream models in the coming years, adaptive headlamp systems automatically manage the direction and intensity of high and low beams. It is a compact solution for shunt FET dimming arrays of high-brightness LEDs and includes 12 individually controlled MOSFET switches to steer current through or around the connected LEDs, thereby providing individual pixel-level light adjustment. www.ti.com
