Infineon speeds up in-vehicle communication and makes it secure and reliable with CAN FD transceivers

Around 60 electronic control units communicate with each other in vehicles today via the Controller Area Network (CAN). The need for in-vehicle communication is growing as the amount of networking increases and more comfort and automation are implemented. The new protocol variant CAN FD (CAN Flexible Data-rate) allows a higher data bandwidth and transmission speed. This saves time in programming, in tests and diagnostic routines as well as for software updates over the air (SOTA).

With its TLE925x CAN FD transceivers, Infineon Technologies makes data exchange up to 30 times faster than today. The TLE925x reaches transmission speeds of up to 5 Mbit/s. Compared to the classical CAN transceivers with a maximum of 8 byte, the CAN FD transceivers such as TLE925x can send a payload of up to 64 byte per message. This opens up the possibility to check the transmitted data for consistency in the transmitting control unit and to sign it with a 21-bit checksum instead of the 17-bit possible so far. Longer checksums ensure reliable communication between the control units. This makes it possible to better secure data transmission in the vehicle without the application software becoming more complex in the electronic control unit.

Highly integrated Hall sensors by Infineon reduce systems costs considerably

The new Hall sensors of Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) enable automotive, industrial and consumer electronics to meet strict environmental standards. Also, they help fulfil the requirements of very cost-effective and compact designs. The Hall sensors of the new TLx496x family are highly integrated, have precise switching points, a stable operation and a low power consumption. They are available as latch and switch-type sensors.

New synchronous rectification ICs for simplicity and efficiency in SMPS applications

Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) released the IR1161L and IR11688S secondary synchronous rectification (SSR) family of Controller ICs to complete Infineon’s product offerings for SMPS applications.

The IR1161L and IR11688S SSR ICs meet the new 2016 standards set by the U.S. Department of Energy and the “European Code of Conduct for Energy Efficiency in Data Centre” which demand a 1 to 3 percent efficiency improvement over previous requirements. Taking 2 percent saving as an average for new adapters, US adult notebook users alone can save 525 GWh per year – which is enough to power New York City for at least 40 days.

Advantages of Using Silicon Carbide in Power Electronics

The advantages of using SiC in power electronics is the focus of a large number of semiconductor news studies and reports.  These reports prove just how advantages using SiC can be when designing power electronics.

Although silicon offers numerous benefits and advantages in power MOSFETs, it also displays some limitations that are characteristic to silicon material properties.  Properties like low thermal conductivity, low bandgap energy, and limitations in switching frequencies.  Power semiconductor devices, however, that are made with silicon carbide (SiC), don’t possess those types of material limitations.
