Description

Top Features

A6260 是一款线性、可编程电流调节器，可提供最高 350 mA 的电流，以驱动高亮 LED 阵列。LED 电流由单个低功率传感电阻器设定，精度为 4%。使用恒流驱动 LED，确保安全运行，并提供最大的可能照明输出。对于汽车应用，它能以高达 350A 的电流驱动 1 至 3 个 LED，实现优化性能。

利用 A6260 的低压差性能可以使用最低 6 V 电源电压全电流安全驱动单个白色 LED。

启用输入可以进行 PWM 调光，并且能用于启用低电流睡眠模式。限制 PWM 开关过程的电流变化率，以降低 EMI。

在任何 LED 端子的对电源或对地电路时提供过电流检测以保护 LED 和 A6260。

集成温度监视器，在芯片温度超过热阈值的情况下减少 LED 驱动电流。

该产品采用带有裸露散热焊盘的 8 引脚 SOIC 封装（后缀 LJ）该封装为无铅产品，引脚框采用 100% 雾锡电镀。

  • 符合 AEC Q-100 汽车级标准
