Texas Instruments (TI) introduced its TCAN1044EV-Q1 Grade 0 CAN FD transceiver and the ISO7741E-Q1 Grade 0 digital isolator for reliable communication and protection in (hybrid) electric vehicle systems that are exposed to temperatures of up to +125 °C (257 °F).
The devices are classified according to the Grade 0 ambient operating temperature specification of the AEC-Q100 (Automotive Electronics Council) standard supporting temperatures of up to +150 °C. The transceiver complies with the ISO 11898-2:2016 and supports Classical CAN and CAN FD networks with data rates up to 8 Mbit/s. The chip comes with an internal logic level translation allowing for interfacing the transceiver I/Os directly to 1.8‑VDC, 2.5‑VDC, 3.3‑VDC, or 5‑VDC logic I/Os. Furthermore, it supports a low-power stand-by mode and CAN Bus wake‑up pattern (WUP). Integrated protection and diagnostic features include thermal-shutdown (TSD), TXD-dominant time-out, supply under-voltage detection, and bus fault protection up to ±58 VDV.
The isolator features a 1.5 kV RMS (root mean square) working voltage and a 5 kV RMS isolation voltage. It allows engineers to shield low-voltage circuitry from high-voltage events in a vehicle’s system. The device can be used in 48‑V HEVs (hybrid electric vehicles) where the co-existence of internal combustion engines and battery systems may heat the air around the ICs above +125 °C. Using the isolator with the CAN FD transceiver increases the in-vehicle network (IVN) signal protection and signal reach as well as applied data-rates.
The ISO7741E-Q1 isolator is available from TI and authorized distributors in a 10,3‑mm x 7,5‑mm 16-pin package. TCAN1044EV-Q1 transceivers are available from TI in 4,9‑mm x 3,91‑mm 8‑pin packages.

The Fully Charged Guide to Electric Vehicles & Clean Energy
Did you know that the carbon impact of producing ten cheeseburgers is the same as one passenger traveling 167 miles on a London bus? Or that high levels of air pollution lead to over 40,000 premature deaths and 6 million sick days each year?
But maybe the future is not as bleak as it seems. What if we told you that by turning down your thermostat by one degree, you could save 320 kg of carbon dioxide annually? And that renewables are already generating a sizeable amount of energy around the world each year?
In The Fully Charged Guide to Electric Vehicles & Clean Energy, experts from around the globe explore how sustainable technology – everything from solar panels to wind turbines and electric vehicles – is getting cheaper, more effective and more available, and how by making everyday changes, we could see the ‘big switch’ in the coming decade.
Presenting the latest innovations in the renewable energy and automotive industries, this book busts myths, provides suggestions and solutions for how to go green, explores how countries around the world are already improving the quality of life of their residents, and looks at where clean energy will take us next.
Many users involved with CAN Bus programming (and exploring the extended capabilities of CAN FD) may not be aware that Classic CAN Bus and CAN FD are excluding each other due to compatibility issues.
