The AH3712 is a latching Hall-effect magnetic sensor, protected for automotive electrical conditions, in a choice of SC59, SOT23 or SIP-3 packaging. The single output is switched ‘on’ with a magnetic pole above a certain flux density, and then switched ‘off’ when exposed to the opposite pole of the same flux density magnitude. There are three parts: AH3712: south pole ...

Taiwan Semiconductor has introduced ten AEC-Q101-qualified small-signal mosfets. There are seven n-channel parts (including two duals), and three p-channel parts (one dual) in the ‘TQM’ line – see the table below. Three packages are used: SOT-236, SOT-363 or SOT-323, and they are rated for >2kV ESD withstanding. “In addition to automotive applications, these small-footprint MOSFETs are ideal for high-reliability commercial designs ...

The third generation of general-purpose neural processing units (GPNPUs) by Quadric introduces pre-integrated clusters of two, four or eight cores to deliver up to 108 TOPS. This latest iteration has increased performance and optimisations for generative AI. the company has also introduced a safety enhanced version for automotive applications. The company described the Chimera QC series as NPUs with a ...

HighTec EDV-Systeme has announced a time-limited evaluation bundle for Autosar-based development using Infineon’s TC4x automotive processors, created with Infineon. In Autosar development, besides a run-time environment and an application layer, ‘basic software’ is needed – which consists of pre-defined modules that are summarised in layers. The layers are intended to make it easier to migrate software to different hardware. One of these ...

Infineon and Swoboda are developing current sensor modules for automotive traction inverters and battery management systems. The deal combines Infineon’s sensor ICs with Swoboda’s expertise in sensor modules, and the first product (photo right) is aimed specifically at Infineon’s ‘HybridPACK Drive G2’ three-phase traction motor drive modules. Later models will cover more general applications. The infineon-specific model is called the ...

At DAC 2024, Efabless celebrated a milestone of 40 commercial companies designed chips using its chipIgnite and Google-sponsored OpenMPW programme. Of these, some are ready for production volumes, the majority are at the prototype/proof of concept stage, said CEO, Michael Wishart. The platform allows start-ups and smaller companies to prototype designs and innovate without having to buy a license, he ...

By 2027, the automotive semiconductor market will see significant growth for logic, memory, microprocessors, analogue, opto, discretes and sensors, says IDC. Auto memory revenue will top $7 billion by 2027 to accommodate larger volumes of source code, map data, media content, and log information while high-speed interface technologies such as PCIe and UFS facilitates real-time data processing and instantaneous feedback. ...

Melexis has qualified a pair of current sensors to UL/IEC 62368-1 for use where ‘reinforced isolation’ is mandated. “Until now, MLX91220 and MLX91221 had only been qualified as a basic, single barrier, isolation device, mandating the need for an engineer to incorporate extra elements like an isolation amplifier into their design,” according to the company. The UL/IEC 62368-1 certification (material ...

The global LiDAR market for automotive is expected to grow from $538 million in 2023 to $3,632 million in 2029 at a 38% CAGR 23-29, says Yole Group. Chinese OEMs are pushing for the integration of LiDAR in their vehicles. In 2024, Hesai and RoboSense are expected to continue leading the passenger car LiDAR market. LiDAR manufacturers are now producing ...

Cambridge electric vehicle battery start-up Nyobolt has revealed a purpose-built testing and demonstration car, created with Callum Automotive of Warwick. “Whilst the priority use for this Nyobolt EV is showcasing and testing the battery technology, Callum’s team has engineered it so that low volume production, for road or track use, is possible,” according to Nyobolt. “Nyobolt’s battery assembly plans are ...
