电议
HCPL-0370/3700 和 HCPL-3760 为电压/电流阀值检测光电耦合器,其中 HCPL-3760 为 HCPL-0370/3700 的低电流版本,为了达到更低电流工作,HCPL-3760 使用了低电流高亮度 AlGaAs LED。器件利用阀值感应输入缓冲芯片,可在宽广输入电压范围内通过单一外部电阻进行阀值控制。
输入缓冲器结合多个功能,例如提高抗噪能力和开关噪声的滞后功能、简化交流输入信号使用的二极管桥式整流电路,以及保护缓冲器和 LED 不受过电压和过电流瞬变破坏的内部箝位二极管,由于在驱动 LED 之前已完成阈值感测,因而 LED 至探测器的光电耦合转换将不会影响阈值水平。
