【应用】国产车规级CAN FD收发器TPT1042Q用于EPS电动助力转向系统，速率高达5Mbps
EPS电动助力转向系统，需要通过CAN总线接口与汽车其他控制系统相连，以获取汽车的相关运行数据(诸如车速、转速及发动机点火信号)，做为EPS系统的控制参数。让这些数据高速、可靠、实时的传输到EPS的控制器进行处理是非常重要的。因而选择适合的CAN总线收发器，是非常关键的。
这里笔者推荐国产思瑞浦的车规级CAN FD收发器TPT1042Q来完成这一任务，主要基于如下考虑：
1、思瑞浦推出的TPT1042Q是一款高性能、高可靠性的CAN FD收发器。满足ISO11898高速CAN标准，满足车规AEC-Q100 Grade 1认证。即使在长距离、重负载情况下依然能保证高达5Mbps的传输速率,用在EPS系统上，可以实现数据的高速、可靠、实时传输。
2、TPT1042Q采用5V电源，I/O电压范围支持2.8V至5.5V MCU接口，支持待机模式，功耗低至5μA。集成了丰富的保护功能(包括IEC 61000-4-2 ESD保护，最高±15kV；共模输入电压：±30V；母线故障保护：±70V；VCC和VIO欠压保护；TXD主导超时功能和总线主导超时功能以及热关机保护功能)，强大的CAN总线耐压能力和高可靠性ESD能力，可保证EPS系统的鲁棒性。
3、TPT1042Q其工作温度范围很宽，从−40℃到+125℃，有SOP8和DFN3X3-8两种封装。如选用DFN3X3-8封装，可以节省EPS系统PCB板的空间和面积，提高可靠性和降低系统成本。
