Melexis has introduced a 40W driver with four half bridges and field-oriented control to operate three-phase brushless motors and four-wire stepper motors. A CPU is included and both sensor-less and sensor-based feedback can be implemented. “For applications requiring flexibility in configuration, MLX81339 offers flash programmability,” said the company. It “ensures reliable start-up, stopping and precise speed control from low to ...

The automotive semiconductor market will grow from $68bn in 2024 to $132bn in 2030 – at a 10% CAGR – five times faster than the automotive market, says Yole. The top five players control half the market, yet emerging challengers are reshaping competition. Infineon leads globally with more than $8bn in automotive revenue in 2024, followed closely by NXP and ...

Nvidia has signed a letter of intent with UK self-driving car startup Wayve Technologies to look at the potential of a $500m investment in the company. Nvidia and Wayve have a seven-year relationship. Nvidia has already invested in Wayve and they collaborate on developing Wayve’s technology, which is based on Nvidia’s Drive AGX Thor technology. This is also used by ...

Nexperia has four announced 100V automotive mosfets in a 12 x 12mm CCPAK1212 legged SMD package. This package saves “up to 40% PCB space compared to traditional TOLL or TOLT-packaged alternatives”, according to the company. There are bottom-cooled (CCPAK1212) and top-cooled (CCPAK1212i, pictured) versions (see table below). On-resistance is between 0.99 and 1.35mΩ, depending on the part, and a copper ...

SiTime has added 0.46 x 0.46mm 0505 CSP resonators to its timing portfolio, with the Titan MEMS platform. They are based on SiTime’s sixth-generation MEMS technology, FujiMEMS and are “at least four times smaller than the smallest legacy quartz alternatives” said the company. The resonators are available either PCB-mounted for customer integration, or as bare die for co-packaging with SoCs ...

Rutronik is to stock automotive wire-to-wire connectors from Adam Tech’s Secur-Seal series. “They support various cable cross-sections and offer suitable seals for every cable thickness to prevent the ingress of water or dust,” according to the component distributor. “They are capable of carrying currents from 5A to 18A, especially in combination with customer-specific cable assemblies.” There are 2, 3, 4, ...

Thanks to TrendForce for this one – the top ten EV vendors in Q1:  

Schaeffler has started mass production of modules for an 800V automotive traction inverter for an un-named Chinese car manufacturer, using silicon carbide mosfets to “increase the maximum possible battery voltage to much more than the usual 800V, and with RMS currents of up to 650A”, said Rohm, which is providing the SiC transistors. “Based on our generic platform development, it ...

TDK has unveiled through-hole aluminum electrolytic capacitors designed to work at up to +140°C for automotive power steering, fan control and transmission systems. They come in axial-lead (B41699) and soldering star (B41799, see photo) types, rated to 25 or 35V, with capacitance ranging from 1,800 to 13,000µF. These are branded as “ultra compact” by the company. Picking a mid-range example, 4,700μF types ...

Bos Semiconductors has shipped its first chiplet-based NPU samples to automotive OEMs. It is a version of the company’s Eagle-N branded processor. “Eagle-N 250Top/s NPU is designed for ADAS (driver-assistance systems), automated driving and in-vehicle infotainment,” said Bos. “Leveraging a chiplet-based architecture, Eagle-N can scale up to 2,000+Top/s.” ISO26262 ASIL-B is the automotive risk target. Neural processor intellectual property within ...
