NXP公司的UJA116xA系列是”自供电”高速CAN收发器,集成了自供电的ISO 11898-2:2016和SAE J2284-1到 SAE J2284-5兼容的高速HS-CAN收发器以及内部5V CAN电源.唯一的电源输入就是电池连接. UJA1161A可工作在非常低电流待机模式和总线叫醒功能. UJA116xA系列产品是硬件和软件都兼容的产品,具有改善的EMC性能.回路延迟对称时序使得在CAN FD快速相的数据速率高达2Mbps时能可靠通信,根据ISO 11898-6进行自主总线偏压.全集成的5V电源(VBUF)用于CAN收发器/接收器.VIO输入允许直接和3.3V到5V微控制器接口,等电源引脚BAT开路时总线连接是真正浮动的.汽车应用时具有8kVESD保护(CAN总线引脚HBM),6kV ESD保护(IEC TS 62228,BAT引脚和CAN总线引脚).在待机模式有非常低的静态电流.主要用在汽车车体控制,车门控制,电动助力转向系统(EPS),排挡变速杆,HVAC,座位安全带预紧装置,车顶控制,压力监视系统(TPMS)和窗户控制等.本文介绍了UJA116xA系列主要特性和优势,框图,应用电路图以及评估板UJA116xA系列EVB主要特性,电路图和材料清单.n
The UJA1161A is a self-supplied high-speed CAN transceiver integrating an ISO
11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant HS-CAN transceiver and an
internal 5 V CAN supply. The only supply input is a battery connection. The UJA1161A
can be operated in a very-low-current Standby mode with bus wake-up capability.
This implementation enables reliable communication in the CAN FD fast phase at data
rates up to 5 Mbit/s.
