The ESDCAN series improves the quality of protection for CAN-FD (flexible datarate), CAN SIC (signal improvement capability) and even CAN XL (extra-long) transceivers without hurting the capacitance budget and reduces the PCB size by 4 compared to conventional solutions.
The autonomous driving megatrend induces a higher electronics content in the car. It deeply modifies the E/E architecture with the coming of Zone Control Units (ZCU) and Vehicle Computer Units (VCUs). These high-density boards can concentrate tens of CAN links making the need to protect CAN transceivers against electrostatic discharge (ESD) and ISO 7637-3 pulses, and requiring high integrated protection solutions. ST offers a wide range of AEC-Q101 CAN protection devices for passenger cars (12 V battery) or commercial vehicles (24 V battery) covering CAN, CAN-FD, CAN-FD SIC, FlexRay and even CAN XL communication protocols. Our devices are housed in 3-lead SOT23 and SOT323 packages as well as in our new extra-small (1.1 x 1.0 mm) wettable flank 3-lead QFN (DFN1110) package allowing AOI (Automatic Optical Inspection).
