【选型】国产RS-485收发器TPT481L1-SO1R助力自动化通信模块,可功能替换SP3078E
随着自动化产品的高速发展,我们周围环绕着各种各样的通信协议,RS-485就是一种相对常见的通信标准。RS-485是一种差分信号标准,除了住宅环境之外,其在商用暖通空调系统、工厂自动化、电网基础设施、电器和电机驱动工业设计中也很常见。本文将基于一款自动化通信主从模块的应用来阐述RS-485收发器在其中的选型设计方案。
有一客户做一个自动化通信主从模块,即是通过485接口、I/O接口等进行细化通信,该产品相当于是一个PLC后端模块,组成比较简单,主要是由主控和通信接口组成,产品主要是应用在工厂里面的工业模块上,一组通信模块共有33个从模块,该产品的输入电压为24V DC,输出5/3.3/1.2V三个规格。该自动化通信模块产品需要的是通信速率高的通信接口,至少达到10Mbps,之前客户用的是SP3078E,速率可以达到16Mbps,因供货及价格等原因选择替换,本文推荐思瑞浦(3peak)的TPT481L1-SO1R进行替换,性能可以满足,能成功做到功能替换的国产替代方案。
思瑞浦的TPT481L1-SO1R是IEC61000 ESD保护的收发器,符合RS-485和RS-422平衡通信标准。热插拔电路-通电/断电期间,Tx和Rx输出保持三种状态,接收器(Rx)输入具有“完全故障安全”设计,如果Rx输入浮动、短路或在端接但未驱动的总线上,则确保逻辑高Rx输出。TPT481与SP3078E的性能指标对比分析如下:
1、TPT481具有宽电源电压3V至5.5V,而SP3078E在所有设备都使用3.3V电源,对比来说,TPT481更具有优势;
2、TPT481总线上最多256个节点(1/8单元负载),速度为20Mbps,而SP3078E上也有多达256个收发器可以共享总线,但速率仅有16 Mbps,比TPT481的速率更低;
3、TPT481具有±18 kV HBM ESD,而SP3078E仅有±15kV ESD,TPT481更具有可靠性;
4、TPT481需要54Ω负载提供特殊的差分输出电压,而SP3078E的高阻抗驱动器输出在-7至+12V的整个共模电压范围内保持不变;
5、两者都有着–40℃至125℃的工作温度范围,满足项目需求。
综上所述,国产RS-485收发器TPT481的各项性能指标较好,而且通信速率也更高,价格与交期更有保障,是485收发器国产替换的优选方案。
