Analog Devices / Maxim Integrated MAX14827A IO-Link 器件收发器

Maxim MAX14827A IO-Link 器件收发器整合了工业传感器（包括驱动器和调节器）中常见的高电压功能。 MAX14827A 配有两个带主动反极性保护的超低功耗驱动器。该操作规定为 24V 额定电源电压，最高达 60V。由于高电压容限允许使用微型 TVS，从而简化了瞬变保护。该器件具有一个柔性控制接口。引脚控制逻辑输入允许采用不使用微控制器的开关传感器进行操作。对于使用微控制器的传感器，可使用一个带多种诊断功能的 SPI 接口。对于 IO-Link 操作，提供一个三线 UART 接口。该接口可连接到微控制器 UART。最后，多路复用器 UART/SPI 选项允许使用一个串行微控制器接口共享 SPI 和 UART 接口。

The Analog Devices MAX14827 is available in compact TQFN-24 and WLP-25 packages and is specified over the extended -40°C to +125°C temperature range.
