25 March 2021 - MELEXIS, a global microelectronics engineering company, has introduced the MLX81117, its latest multichannel RGB LED driver. This new product supports the MeLiBu™ high-speed communication licence-free IP which enables intelligent animated automotive lighting concepts.

The technology is already being leveraged by leading global car manufacturers to enhance the safety features of their latest models. The MLX81117 extends the MeLiBu product family with even better color-mixing accuracy of delta UV of <0.01.

Car manufacturers continue to adopt animated lighting in the cabin, to provide important information such as driver-assistance prompts, vehicle status updates or advanced comfort functions like adaptive roof light. It is becoming increasingly mainstream to use RGB LED lightbars to communicate with the driver through color-coded, color-changing and blinking sequences. However, this presents engineering challenges, such as maintaining consistent color across all of the LEDs in the lightbar and implementing simultaneous light changes.

The MLX81117 addresses this by integrating the Melexis MeLiBu high-speed communication interface IP. MeLiBu controls individual LEDs to implement the lighting effects defined by the vehicle's systems. The intelligent RGB-LED controller also provides real-time compensation of any color drift caused by environmental changes, and color-mixing accuracy with a delta UV of <0.01% to eliminate any distinguishable differences between LEDs.

The MeLiBu communication interface uses a CAN-FD physical layer to deliver robust and reliable performance at up to 2 Mbit speeds. MeLiBu also delivers intelligent and high resolution operation to mitigate temperature-related color drift, to maintain a consistent and non-distracting user experience under all operating conditions.

The MLX81117 LED driver IC's additional features include brightness control across a wide dimming range, which allows adjustments for natural light levels. The MLX81117 complies with ISO 26262 functional safety requirements up to safety integrity level B (ASIL B) and the design also delivers low EMI and high levels of immunity, helping designers to meet EMC regulations.

“The MLX81117 is the second product offering from Melexis to integrate its MeLiBu technology, which enables a scalability approach of the lighting system as well as new application functions,” said Michael Bender, Product Line Manager Embedded Lighting, Melexis. “It extends our support for advanced light functionality and we are excited to see leading automotive manufacturers already include it in their new models to deliver a safer driving experience.”

请问世强的大佬们：1、Melexis三轴霍尔传感器MLX90333工作电压在3.3V是否能正常工作？ 2、Melexis三轴霍尔传感器MLX90333三种输出模式是否都需要专用的编程器PTC04来进行编程后才能使用？3、如果需要编程，在哪儿可以买到已经设置成模拟电压输出的芯片？

1、Melexis品牌的3D霍尔传感器MLX90333正常工作电压是5V，最小工作电压是4.5V，所以在3.3V不能正常工作。2、MLX90333需要编程器PTC04+子板的方式来编程，否则就是2.5V电压输出。3、预编译版本的霍尔传感器可以选择MLX90316版本，但是磁铁、机械结构必须严格按照MLX90316的要求来设计，否则无法满足MLX90316预编译版本的精度。
