Automotive-Compliant, Three-Channel, Linear LED Driver From Diodes Incorporated Provides Independent Controls for Brightness and Color
Diodes Incorporated (Diodes) (Nasdaq: DIOD) today releases a new automotive-compliant* linear LED driver that enables users to independently control the brightness and color of its three channels.
Diodes 公司（Diodes）（纳斯达克股票代码：DIOD）今天发布了一款符合汽车标准的新型*线性 LED 驱动器，使用户能够独立控制其三个通道的亮度和颜色。
Human-centric automotive design is driving the demand for multi-channel LED drivers, which allow vehicle occupants to easily change interior lighting colors to match their mood. By simultaneously enabling animated turning-indicator signals and exterior grill lighting for different road conditions, these drivers help increase safety levels. The AL1783Q driver has LED current settings by an external REF pin, independent dimming controls for each channel, and pulse width modulation (PWM) to perform LED dimming. It is well-suited for multiple interior and exterior lighting applications in electric vehicles (EV) and internal combustion engine (ICE) vehicles.
以人为本的汽车设计推动了对多通道 LED 驱动器的需求，这使车辆乘员能够根据自己的心情轻松更改内部照明颜色。通过同时启用动画转向指示灯信号和适用于不同路况的外部格栅照明，这些驾驶员有助于提高安全水平。这个 AL1783Q 驱动器具有通过外部 REF 引脚设置 LED 电流、每个通道的独立调光控制以及用于执行 LED 调光的脉冲宽度调制 (PWM)。它非常适合电动汽车 (EV) 和内燃机 (ICE) 车辆的多种内部和外部照明应用。
The automotive industry is trending towards using higher voltage rails to power vehicle subsystems and this has seen battery voltages increasing from 12V and 24V to 48V. In response to this development, the AL1783Q has been designed to operate from a 55V rail, providing it with an advantage over other LED drivers which typically only operate up to 40V. This feature also enables the AL1783Q to support increasing LED chain voltages.
汽车行业倾向于使用更高的电压轨道为车辆子系统提供动力，这使电池电压从 12V 和 24V 增加到 48V。为了应对这一发展，AL1783Q 被设计为在 55V 电源轨上运行，这使其比通常只能在 40V 的电压下运行的其他 LED 驱动器更具优势。此功能还使 AL1783Q 能够支持不断增加的 LED 链路电压。
Another advantage of this driver is that it delivers up to 66% more current per channel (250mA compared with a standard 150mA), enabling greater flexibility to support higher LED current ranges in a wider range of lighting applications. For additional flexibility, the current in each of the three channels can be set using individual resistors.
该驱动器的另一个优点是，它每通道可提供高达 66% 的电流（与标准 150mA 相比，电流为 250mA），从而能够更灵活地在更广泛的照明应用中支持更高的 LED 电流范围。为了提高灵活性，可以使用单独的电阻器来设置三个通道中每个通道的电流。
Thermal robustness is an important consideration when designing with linear LED drivers and, for this reason, the AL1783Q is housed in a thermally efficient TSSOP-16EP package that has an exposed cooling pad for superior heat dissipation. For added system level reliability, the AL1783Q has multiple fault detection features including undervoltage lockout (UVLO) and overvoltage protection (OVP), as well the ability to detect LED open and short circuit conditions.
使用线性 LED 驱动器进行设计时，热稳定性是一个重要的考虑因素，因此，AL1783Q 采用散热效率高的 TSSOP-16EP 封装，该封装具有外露冷却垫，可实现卓越的散热效果。为了提高系统级可靠性，AL1783Q 具有多种故障检测功能，包括欠压闭锁 (UVLO) 和过压保护 (OVP)，以及检测 LED 开路和短路情况的能力。
The AL1783Q is automotive compliant* — qualified to AEC-Q100, manufactured in IATF 16949 certified facilities, and supporting PPAP documentation. Supplied in the space-saving TSSOP-16EP (5.1mm x 6.6mm) package, the AL1783Q is available at $0.43 in 2,500 piece quantities.
这个 AL1783Q 符合汽车标准* — 符合 AEC-Q100 标准，在 IATF 16949 认证设施中制造，支持 PPAP 文档。AL1783Q 采用节省空间的 TSSOP-16EP（5.1 毫米 x 6.6 毫米）封装，售价 0.43 美元，批量生产 2,500 件。
