Maxim Integrated Maxim MAX14824 IO-Link® 主控收发器

Maxim Integrated MAX14824 IO-Link® 主控收发器 是一个IO-Link主控接口，它在一个IO-Link物理层收发器上集成了两个辅助数字输入接口和两个线性稳压器。通过带内系统编程接口（SPI）寻址，可支持高端口数IO-Link主控应用。12MHz SPI接口减少了主控制器的访问次数。带内寻址和可选SPI地址帮助实现级联最高16部设备。Maxim MAX14824支持各种IO-Link数据速率，并带有转换速率受控型驱动器来降低电磁干扰（EMI）。驱动器可稳定驱动高达300mA（最小值）的负载电流。内部唤醒电路自动确定正确的唤醒极性，从而允许使用简单通用异步收发器实现唤醒脉冲的生成。MAX14824可工作于扩展的-40℃到+105℃的温度范围。
