【应用】基于硕凯电子国产GDT、PTC和TVS设计的汽车CAN总线防护方案
CAN是控制器局域网络(Controller Area Network)的简称,CAN总线传输距离较远,易受电磁环境干扰。本文将介绍基于硕凯电子的GDT、PTC和TVS设计的汽车CAN总线防护方案。
一、防护电路图
二、应用背景
1、雷雨天气增多
2、CAN总线传输距离较远
3、CAN传输速率最高可达1Mbps
4、易受电磁环境干扰
三、方案应用
1、汽车电子
2、通信设备
四、方案说明及注意事项
1、前端采用通流量大的GDT,泄放大电流
2、后级采用反应时间快的TVS,残压低,有效保护CAN控制芯片
3、中间采用PTC做退藕,让前端GDT更容易动作,达到泄放电流作用
4、本方案满足IEC61000-4-2、GBT1762.2等静电标准,IEC61000-4-5、GBT1762.5等浪涌标准
5、本方案在差模、共模均采用的是同型号的TVS和GDT,防护无死角
6、可通过10/700μS(等效内阻40ohm)、1.2/50-8/20μS测试,具体防护等级需参考GDT和TVS的通流量
