TI for adaptive automobile headlight system introduced the industry's first comprehensive integrated LED matrix manager
Recently, Texas instruments (TI) announced the industry's first adaptive car headlights system oriented comprehensive integrated manager highlighted LED matrix of IC. The launch of TPS92661 - Q1 is a small extensible solution, can help automobile manufacturers to create a dynamic change beam pattern and intensity of innovative LED headlights, which can achieve the best effect of road lighting, and improved the security of the driver. If you would like to know more details, obtain samples and evaluation board, please visit: www.ti.com.cn/tps92661q-pr-cn.
The adaptive system can automatic management of high and low beam headlights direction and intensity of current is mainly used for high-end cars, in the next few years will also be applied to the mainstream models. TPS92661 - Q1 is a suitable for high brightness LED shunt FET array of small solution that move light, contains 12 respectively control the MOSFET switch, can guide the current connection through or bypass the LED, to support a single pixel level dimmer. Serial communication port help through the main microcontroller (such as TI accord with standard of AEC - Q100 C2000 ™ Piccolo ™) control and diagnosis function.
Up to now, the design of adaptive headlights headlights beamforming and direction control circuit board still needs a lot of space to accommodate multiple transistors, logic gate drives and adhesive etc. Large discrete circuit. Single TPS92661 Q1 - not only can replace the complicated design, plunged 73% will board space, but also can realize headlights system of all solid state, no moving parts, to avoid moving parts wear problem such as motors or actuators.
TPS92661 - main features and advantages of Q1
From a single serial port control, can be up to 96 LED to achieve beamforming headlights and direction control;
A single 10 pulse width modulation (PWM) brightness control LED light intensity at pixel level adjustment can be realized;
LED open/short circuit fault diagnosis and fault or damage to the case report in the headlights through the main microcontroller to remind the driver.
The supply position and encapsulation
Using 48 pins HTQFP encapsulation TPS92661 - Q1 has now begun batch supply, can be ordered by TI and its authorized distributors.
LED tools and support
Order is suitable for the automobile exterior lighting TPS92661EVM - 001 assessment of the board, it can demonstrate a single PWM dimming control of each LED.
