概览
NCV78247 是一款单芯片像素控制器，带嵌入式开关，可控制串联 LED 串中的 LED，适用于汽车照明应用，特别适合高电流 LED。要实现像素光方案，LED 需要优先使用当前的电源，如 NCV78763 、NCV78723/713 或 NCV78825 LED 驱动器供电。NCV78247 像素控制器器件接收来自像素光 ECU 的像素控制参数，该 ECU 将所需的光带或光图像转换为单个像素调光信息。一个像素控制器器件可以控制高达 12 像素，每像素 1 个、2 个、3 个或 4 个 1A LED。LED 串最大电压必须限制在 60v。如果需要控制的像素超过 12 个，则可在一个系统中组合多个像素控制器。12 个集成开关通常排列为 12 个 1 A 的开关，但也可以排列为 6 x 2 个并联开关，形成 6 个 2 A 开关。除了支持两串 6 个 LED 的配置外，还可以支持其他变体。
