In a bid to meet the increasing demand for customizable lighting solutions in automobiles, Diodes Incorporated has announced the release of the AL1783Q, a new automotive-compliant linear LED driver. This cutting-edge technology allows users to independently control the brightness and color of its three channels, setting a new standard for lighting applications in electric and internal combustion engine vehicles.
The surge in human-centric automotive design has fueled the need for multi-channel LED drivers. With the AL1783Q, vehicle occupants can easily tailor interior lighting to match their mood, enhancing the overall driving experience. Moreover, the driver supports animated turning-indicator signals and exterior grill lighting, contributing to heightened safety levels on the road.
In response to industry trends, where higher voltage rails are becoming the norm, the AL1783Q operates from a 55V rail, giving it a distinct advantage over competitors limited to 40V. This feature not only aligns with the evolving automotive landscape but also ensures compatibility with increasing LED chain voltages.
Flexibility is a key feature of the AL1783Q, offering up to 66% more current per channel (250mA compared to the standard 150mA). This enables greater support for a wide range of lighting applications, and individual resistors can be used to set the current in each of the three channels, allowing for highly customizable options.
Thermal efficiency is a crucial consideration in the design of linear LED drivers. The AL1783Q addresses this concern by being housed in a TSSOP-16EP package with an exposed cooling pad, facilitating superior heat dissipation. The driver also boasts multiple fault detection features, including undervoltage lockout (UVLO) and overvoltage protection (OVP), adding an extra layer of reliability by detecting LED open and short circuit conditions.
Meeting automotive compliance standards, the AL1783Q is qualified to AEC-Q100, manufactured in IATF 16949 certified facilities, and supports PPAP documentation. Packaged in the space-saving TSSOP-16EP (5.1mm x 6.6mm), the AL1783Q is available at a competitive price of $0.43 in 2,500 piece quantities. This release marks a significant stride in the realm of automotive lighting, offering advanced features to meet the evolving needs of the industry.
