Creating design industrial and automotive systems that meet or exceed EMC and ESD requirements without external noise filtering is a challenge -- but it just got easier.
In today's stringent safety requirement world, there's now help for designers in the industrial and automotive segments who need to meet compliance. A family of robust CAN transceivers was designed and introduced by Freescale Semiconductor, specifically addressing high-speed performance and reliability.
The chokeless CAN high-speed physical layer transceivers deliver high EMC and ESD performance, necessary in automotive and harsh industrial applications where networked electronic systems and devices are packed together. Freescale gets the quiescent current down to 8 mico amps and has implemented fail-safe features in both the MC33901 and MC34901 transceivers.
Both devices convert digital protocol data into analog CAN communications in such applications as safety-critical industrial motor control, factory automation, and industrial robotics on the industrial side, and for the automotive industry, automotive body electronics, power train, and infotainment systems.
Features include robustness that exceeds stringent EMC and ESD requirements (±6kV ESD, >36Bm DPI), support for long-length CAN node interconnects for industrial applications, and such industry-specific product options as built-in transmission dominant timeout feature in the MC33901 for automotive use, and built-in support for long-length and low baud rate networks in the MC34901 for industrial apps.
Freescale is offering designers market-specific feature sets, a small form factor evaluation board, and OEM certification reports from external labs -- click here. Both devices are planned to be out in the second quarter of 2014. Sounds like this will help shave some time off getting products to market.
