High-speed CAN transceivers from TI feature ESD protection

Texas Instruments has introduced two new 5V Controller Area Network (CAN) transceiver chips which are compliant with ISO 11898-2 and ISO 11898-5 standards for automotive networking. To protect the devices from high electrostatic discharge (ESD) particularly important in electric and hybrid cars, Texas instruments has designed these CAN transceivers to withstand electrostatic discharge of 8 KV for contact discharge and 15 kV for air discharge. HVDA551-Q1 and HVDA553-Q1 offer two device configurations and meet the requirements of US OEM testing without the need for external protection diodes and common-mode choke. These ICs are suggested for automotive body control modules, infotainment and advanced driver assist systems (ADAS), vehicle gateway nodes and rear-view camera modules.

Designers have two transceiver choices to meet their system requirements, the HVDA551-Q1, with the ability to shift IO level voltages; and the HVDA553-Q1 with a common- mode bus stabilization output.

System protection: Both devices also have under-voltage lock-out (UVLO) protection and dominant state timeout features.
