Macroblock launches LED driver IC for automotive

Macroblock Inc. (MBI) has had its LED driver IC MBI5353Q certified to AEC-Q100 Grade 1 for the automotive sector. With a wide operating temperature range from -40°C to +125°C, the MBI5353Q is the ideal automotive solution for the many different automotive displays and other relevant automotive parts.

The Automotive Electronics Council (AEC) is a U.S. organization founded in the 1990s by Chrysler, Ford, and GM that introduced standardization of the qualification of electronic components in the automotive supply industry to ensure safety and reliability in this sensitive area. AEC-Q100 is now the general standard and is considered a complete collection of automotive qualification specifications, particularly with regard to LEDs and their ambient temperature range.

The MBI5353Q is qualified to AEC-Q100 Grade 1 and supports an operating temperature range from -40°C to +125°C. In these harsh environmental conditions, component performance and quality are critical. The 48 channel LED driver IC provides support for up to 32 scan designs. Each individual IC can control up to 1536 points. It is also capable of supporting a high number of zones and multiple independent single point controls, which is useful in new automotive applications such as the LED tail light strip.

The MBI5353Q is suitable as a solution for the digital cockpit and the central infotainment display. By using direct illuminated LED backlighting in the LCD with multi-channel driver ICs in time division multiplex design, the light can be individually controlled to dim locally. This driver not only enhances the dynamic contrast ratio, but also solves problems such as unnecessary energy loss and product warming by independently controlling the brightness of the LEDs and putting the driver ICs that are not needed into energy-saving mode.

Macroblock is committed to the development of LED driver IC technology and is continuously expanding its automotive portfolio. The best LED driver IC's from Macroblock can be found at Neumüller Elektronik.
