Maxim Announces Industry's First Remote Tuner Solution with Single Hardware Platform Supporting Worldwide Radio Standards for Automotive Applications

MAX2175 RF to Bits® tuner-based solution reduces cables and simplifies vehicle head unit design

Using the remote tuner solution from Maxim Integrated Products, Inc. (NASDAQ: MXIM), designers can significantly simplify the head unit design of a vehicle and reduce cables. The MAX2175 RF to Bits tuner within the solution eliminates the need to rework the vehicle's hardware to support worldwide radio standards, allowing updates by simply changing the vehicle's software.

Traditional radio architecture brings many challenges to vehicle designers. The vehicle's complex head unit must accommodate multiple tuners, manage heat dissipation, and receive multiple cables from the antennas. In addition, the received analog signals pick up noise as they travel from the antenna to the head unit of the vehicle. Finally, baseband processing uses single purpose hardware, requiring separate designs to support multiple worldwide radio standards.

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.

ROHM's Isolated Power Supply Control ICs for Industrial Inverters

No optocoupler or auxiliary winding contributes to greater miniaturization, power savings, and reliability

ROHM has recently announced the availability of isolated flyback-type DC/DC converter control ICs for inverters in high power industrial equipment such as FA/solar inverters and power storage systems.

Isolation is almost always built into electronic equipment to provide protection against shock and damage. High voltage, high power industrial applications (including power storage systems and solar inverters which are seeing increased adoption) are no exception, requiring even more stringent reliability demands due to the harsher temperature conditions and the need for continuous, long-term operation.

New 1700V SiC MOSFET and Control IC Evaluation Board from ROHM Semiconductor

ROHM Semiconductor has recently announced the availability of a new 1700V SiC MOSFET optimized for industrial applications, including manufacturing equipment and high-voltage general-purpose inverters.

In recent years, the growing trend to conserve energy in all areas has increased the demand for energy-saving power semiconductors, particularly for applications in the industrial sector such as general-purpose inverters and manufacturing equipment. In the majority of auxiliary power supplies, which are used to provide drive voltages for power supply circuits, control ICs, and various supplementary systems, high breakdown (1000V+) silicon MOSFETs are normally utilized. However, these high-voltage MOSFETs suffer from large conduction loss (often leading to excessive heat generation), and present problems related to mounting area and the number of external components, making it difficult to reduce system size. In response, ROHM developed low-loss SiC MOSFETs and control ICs that maximize performance while contributing to end-product miniaturization.
