Texas Instruments (TI) (NASDAQ: TXN) today introduced the industry's first fully integrated high-brightness LED matrix manager IC for adaptive automotive headlight systems. The TPS92661-Q1 is a compact, scalable solution that enables automobile manufacturers to create innovative LED headlamps that vary beam patterns and intensity dynamically for optimum roadway illumination and enhanced driver safety. For more information, samples and evaluation modules,
TI will demonstrate the TPS92661-Q1 in booth #217 at the SAE Convergence Conference and Exhibition inDetroit, Mich., Oct. 21-22.
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. The TPS92661-Q1 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. A serial communication port facilitates control and diagnostic functions from a master microcontroller, such as TI's AEC-Q100-qualified C2000 Piccolo.
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-percent, and enables a headlamp system that is completely solid state with no moving parts that can wear out, such as motors or actuators.
