Texas Instruments launches the industry’s first fully integrated high-brightness LED matrix manager IC for adaptive automotive headlight systems, reports MarketWatch.

The TPS92661-Q1 will enable the designing of advanced LED headlamps that differs beam patterns and intensity for optimum roadway illumination along with driver safety.

These headlights are featured in premium vehicles, multiplying into mainstream models in future.

These adaptive headlamp systems can automatically manage the direction and intensity of high and low beams. It is also a solution for push FET dimming displays of high-brightness LEDs that consist of 12 individually controlled MOSFET switches to control current through the LEDs, providing individual pixel-level light adjustment.

A serial communication port enhances control and diagnostic functions from a master microcontroller like TI’s AEC-Q100-qualified C2000 Piccolo.

A single TPS92661-Q1 replaces old board space that included bulky circuits with multiple transistors and gate drivers, reducing space by 73-percent, and enables a solid state headlamp system with no wearing out moving parts.

In addition, this system controls up to 96 LEDs from a single serial port for headlamp beam forming and directional control. They have individual 10-bit pulse-width modulation (PWM) brightness control for pixel-level light intensity adjustment.

Besides, the LED open/short fault diagnostics and reporting alerts driver through the master microcontroller in the event of headlamp failures or damage is an enhanced feature.
