Maxim MAX22513浪涌保护双路IO－Link收发器解决方案
Maxim公司的MAX22513是双路低功耗IO-Link收发器,具有可选择的控制接口,内部高效率DC/DC降压稳压器,两个线性稳压器和集成了用于鲁棒通信的浪涌保护.器件还有低开态电阻驱动器(C/Q和DO/DI),可选择驱动电流限制和过流保护以降低功耗.DC/DC降压稳压器提供多达300mA负载电流和可调整输出电压(2.5V-12V).而内部线性稳压器产生5V和3.3V,提供高达50mA电流.MAX22513可通过SPI或I2C接口,灵活接口微控制器,支持全双工和半双工SPI.内部的MCLK振荡器为IO-LINK通信的微控制器提供时钟源.工作温度-40℃到 +125℃,主要用在IO-Link传感器和执行机构装置以及工业传感器.本文介绍了MAX22513主要优势和特性,框图和I2C接口应用电路图,半双工SPI接口应用电路图以及评估板MAX22513 EVK主要特性,框图,电路图,材料清单和PCB设计图.
The MAX22513 dual-channel low power IO-Link device transceiver features a selectable control interface, internal high-efficiency DC-DC buck regulator, two internal linear regulators, and integrated surge protection for robust communication. The device features low-on resistance drivers (C/Q and DO/DI), selectable driver current limits, and overcurrent protection to reduce power dissipation in small sensor applications.
The DC-DC buck regulator supplies up to 300mA load current and has an adjustable output voltage (from 2.5V to 12V). Internal linear regulators generate 5V and 3.3V, supplying up to 50mA of current.
