一种LED汽车动态转向灯驱动电路

A Drive Circuit Designed for Automotive LED Dynamic Cornering Light

基于TPS92630驱动芯片,采用MCU控制LED的亮灭时序,设计出LED动态转向灯驱动电路。MCU根据处理的数据输出控制信号循环点亮各组LED灯珠,形成渐亮的流水式视觉效果。该电路对时序的控制比较精准,且关于组合灯形式的车灯,对于时序先后、延时的控制也更为方便。

A drive circuit based on TPS92630 and MCU to control the LED light was designed to provide a dynamic cornering light. The MCU will output control signal to lit LED lamps in turn according to the processing data, to form coming on stream visual effect. The control of timing of this circuit is more accurate, and it is more easily for the circuit to control the sequence and time delay of LED lights when the dynamic cornering light is combined light form.
