SN65HVD231: 支持热插拔

Part Number: SN65HVD231

Hi 

如题,SN65HVD231规格书写Glitch-Free Power-Up and Power-Down CAN Bus Protection for Hot-Plugging ,也就是说热插拔不会对总线有影响吗?设计上需要注意什么吗?

  • 您好,是的这款CAN收发器支持热插拔,并且在热插拔过程中,内部集成了power up/down的glitch free电路。因为热插拔最容易导致的就是glitch或者surge,器件内部已经集成了这些浪涌或者ESD保护,如果应用需求高于器件的规格,那么也可以考虑通过外部电路的形式,比如TVS瞬态抑制器件,能有效的保护收发器免受这些可能导致损坏的高功率瞬变的影响。
