Electromagnetic compatibility (EMC) and electrostatic discharge (ESD) are critical requirements in harsh industrial and automotive environments due to the close proximity of a wide range of networked electronic systems and devices. Freescale’s MC33901 and MC34901 chokeless CAN high-speed physical layer transceivers deliver outstanding EMC performance and high ESD robustness without the need for external components, thereby reducing overall system costs. The devices also offer fail-safe features to assist with system functional safety, as well as exceptionally low quiescent current down to 8 micro amps.

The MC33901 and MC34901 products convert digital protocol information into analog CAN communication across in-vehicle networks, as well as long-length CAN node interconnect for industrial applications. The devices are suited for a broad range of applications including safety-critical industrial motor control, factory automation and industrial robotics systems, as well as automotive body electronics, power train and infotainment systems. Both products offer high performance at 2 Mbps baud rate to address CAN FD (flexible data) application requirements.
