Cambridge-based Titan has announced a steer-by-wire system for vehicles “from electric hypercars to automated trucks which has been designed to meet demand from lower-volume manufacturers who need a bespoke system”, it said. The 48V electric motor that operates the steering rack was developed in-house along with the rest of the mechanical system and the control unit. All of it is ...

Melexis is claiming 1% accuracy over temperature and life for its latest galvanically-isolated Hall effect current sensor. “MLX91230 guarantees this accuracy not only for thermal drift but also lifetime drift and linearity errors,” according to the company. The 8pin SOIC device is AEC-Q100 and ASIL compliant, supporting system integration up to ISO 26262 ASIL D functional safety requirements. Current measurement ...

As the curtain has just risen on IAA Mobility 2023 in Munich on September 5, the leading Chinese provider of CMOS mmWave radar chips, Calterah, brings a most comprehensive portfolio of automotive radar SoCs at Booth A2-F31 of Mess München to the global audience. Figure 1 Visitors Showing Great Interest in Calterah mmWave Radar SoCs (please click on images to ...

Bel Fuse has released a second generation of its kW-class dc-dc converter for powering accessories from an electric or hybrid vehicle battery. Rated at 4kW, 700DNG40-24-8 is smaller and, at 450 to 900Vdc, operates over a wider input voltage range than its 700DNC40-24-8G predecessor. Size is 285 x 55 x 355mm including protrusions, and it weighs 4.5kg. The galvanically-isolated output ...

At Semicon Taiwan, Navitas Semiconductor announced GaNSafe, its fourth generation GaN technology. It is designed in a TOLL package to be rugged and protected in demanding environments and suitable for commercial applications in data centres, inverters in solar panels and onboard chargers in electric vehicles. The choice of a TOLL reduces the size compared to a QFN, explained Stephen Oliver, ...

New sensor and processing technologies will lead to safer roads, says Chet Babla, of Indie Semiconductor. Road traffic accidents kill 1.3 million people every year, with countless others injured. Many of these accidents involve human error and are potentially avoidable. While the ultimate goal of the ‘uncrashable’ car may still be some way off, the level of vehicle automation is ...

Only a few weeks ago Onsemi announced that its silicon carbide power transistors are to be used in BorgWarner Viper electric vehicle traction inverters, and now STMicroelectronics has revealed something similar. “STMicroelectronics will supply BorgWarner with third-generation 750V silicon carbide power mosfet die for their proprietary Viper-based power module,” according to ST. “This power module is used in BorgWarner’s traction ...

Vehicle manufacturers have long dreamt of reducing weight by replacing heavy wiring looms with radio frequency technology. However, achieving this wireless nirvana is not as simple as it first appears, writes Sampson Hu, founder of UK antenna specialist Novocomms. One of the heaviest sub-systems in most vehicles, wiring harnesses can weigh in at around 150lbs, creating a major headache for ...

Rohm has developed Hall-based magnetic detectors for vehicle use. BD5310xG-CZ types are momentary (dubbed ‘unipolar’): turning on above a fixed south pole magnetic flux density and turning off below the same threshold (with a small amount of hysteresis) BD5410xG-CZ types are latching: turning on above a fixed south pole flux density, then remaining on until an equal north pole flux ...

Diodes has announced a single-channel version of its automotive-qualified AS2333Q dual precision micro-power op-amp. AS333Q has an 8μV input offset (22μV max 25°C), consumes 17μA, and has “near zero-drift over time and temperature for high-accuracy signal conditioning in automotive electronic control units”, according to the company. It has rail-to-rail inputs and output, with the common-mode range extending 100mV beyond the ...
