Fraunhofer Institute for Microelectronic Circuits and Systems IMS has had a version of its 32bit AIRisc RISC-V microcontroller intellectual property certified by by TÜV SGS to the ISO 26262 ASIL-D automotive safety standard. Called AIRisc-Safety, it can now be licensed from the organisation, which also offers customised versions for asic and FPGA integration. “Certification means that industrial customers directly receive a ...

Toshiba has introduced a brushless dc motor driver that supports ASIL-D for functional safety in vehicles. Designed in accordance with ISO 26262 (2nd edition) and AEC-Q100-qualified, TB9083FTG is aimed at electric power steering, electric braking and shift-by-wire transmissions. “A built-in fail-safe safety relay pre-driver complements the three-phase pre-driver,” according to the company, and the “SPI communication interface features an integrated ...

Aiming at electric vehicle traction inverters, LEM has managed to shrink a 1.5kA current sensor into 29 x 21 x 12mm and 27g. “HSTDR current sensor is significantly more compact than a traditional C-core sensor, making it much easier to be integrated into space-limited inverter boxes,” said LEM. The technology is open-loop Hall effect and the core, integrated bus bar ...

February is definitely the month for automotive high and low-side drivers, proved beyond doubt as Diodes has just followed Rohm, Toshiba and STMicroelectronics with its contribution: a protected 4A (25A pulsed) high-side switch. Called ZXMS81045SPQ, it operates across 5 – 28V (41V abs max) and responds to both 5V and 3.3V logic inputs. Packaging is SO-8 with an exposed heat sinking ...

After a flat market in 2022, car sales will grow 3.8% this year to 84.1 million vehicles , says TrendForce 26.9 million cars were sold in China in 2022 – iup 3.7% on 2021. In the US  13.7 million cars were sold which was an 8.1% decline y-o-y. In Western Europe 11.8 million cars were sold – a 4.6% y-o-y ...

Kyocera has introduced AEC-Q200 qualified supercapacitors for automotive use. To be found in the company’s SCC series, there are four capacitors (diameter x length): 35F 3V SCCU30E356SRBQ (16  x 30mm) 50F 3V SCCV40E506SRBQ (18 x 40mm ) 100F 2.7V SCCV60B107SRBQ (18 x 60mm) 100F 3V SCCV60E107SRBQ (18 x 60mm) where the final Q indicates AEC-Q200 qualification “They can be used ...

Chomerics has announced a thermal interface material with thermal cycling and high temperature  performance aimed at automotive components. Called ‘GEL 20’, it is a one-component material that requires no secondary cure and offers 2.4W/mK conductivity. Operation is over -55 to +200°C. “The material’s heavy paste-like consistency enables controlled dispensing, applied in variable thicknesses up to 4mm,” according to the company. ...

It seems to be the week for high and low-side driver announcements, with STMicroelectronics now following on from Toshiba and Rohm. ST’s offering are, like Rohm’s, for automotive use. They are single, double and quad high-side gate drivers in a common 6 x 4.9 x 1.7mm gull-wing thermal pad package, “with pin assignments that simplify scaling circuit designs to add ...

Rohm has released one and two channel 40V low-side switches with AEC-Q100 qualification for automotive and industrial use. BV1LExxxEFJ-C (single-channel, 4.9 x 6 x 1mm HTSOP-J8) and BM2LExxxFJ-C (dual-channel, 4.9 x 6 x 1.65mm SOP-J8) “are suitable for systems such as car body control, engine and transmission control units, LED lighting modules or industrial programmable logic controllers”, according to the ...

According to Sourcengine, the automotive IC shortage will last throughout 2023, with supply not balancing with demand until Q4 2024 or Q1 2025. DRAM is on 20-26 weeks lead time from Micron and Samsung rising to 26-30 weeks for DDR3 and DDR4. NAND is on 20-26 weeks from Kioxia General Discretes are on 20-36 weeks at ST, 20-32 weeks at ...
