Andes and Green Hills are to develop an integrated automotive compute offering for IC designers based on the AndesCore 25-Series RISC-V processor IP including the safety-certified µ-velOSity RTOS, the ASIL-certified MULTI development environment with advanced system-level debugging and analysis tools and C/C++ Optimizing Compilers, along with the Green Hills Probe for JTAG and trace target connections. The combined product is designed for ...

Californian GaN power IC maker Navitas Semiconductor has bought Virginia silicon carbide company GeneSiC Semiconductor. “Navitas GaN ICs are optimised for 400V electric vehicle systems, and GeneSiC technology is ideal for 800V electric vehicle systems,” according to Navitas. “Navitas GaN ICs serve residential solar, while GeneSiC has immediate revenue in higher power commercial solar and energy storage customers. GeneSiC high-voltage ...

Diodes has announced a 600mA automotive-compliant dc-dc converter that can run from 4.5 to 40V. Called AP64060Q, the parts include a 600mΩ high-side and a 300mΩ low-side mosfet – the latter making an external Schottky optional. Quiescent current is typically 90μA, according to the company. Two resistors are needed to set output voltage, and anywhere up from 0.8V – with ...

Recom has launched a range of 500W IP-67-enclosed dc-dc converters for powering loads from off-highway electric vehicle batteries. Called RMOD500-W, the supplies have an input range of 32 – 96V, which spans nominal 48V, 60V, 72V and 80V batteries. Depending on the unit, the output is 24.5, 23.5, 13.7, 13, 12.4 or 11.7V, and paralleling can be used to increase ...

Murata has introduced a series of chip ferrite beads with a 20A current rating, aiming them at the battery charging systems and powertrains of electric vehicles, as well as in industrial equipment. Called the BLE32SN series, its members are 3.2 x 2.5 x 2mm (1210 or metric 3225) and operate over -55 to +125°C or -55°C to +150°C. “By leveraging ...

Nexperia is aiming at protecting USB 3.2, HDMI 2.0 and LVDS data lines in vehicles with family of ESD (electrostatic discharge) protection diodes. “Additionally, this portfolio also aims to address the upcoming high-speed video-links as well as the Open Alliance multi-Gbit Ethernet applications”, according to the company. All variants come in 1 x 0.6 x 0.5mm leadless packages to improve ...

With bidirectional charging, solar power from a photovoltaic system can be stored in electric cars and fed back into the home grid when needed. Infineon and Delta have developed a three-in-one-system that integrates solar, energy storage and charging of electric vehicles. Thanks to bidirectional inverters, the electric car is not only charged, but can also be used as a buffer ...

ST and VW’s software unit Cariad are joining up to co-design automotive chips and are “moving to agree” that TSMC will fab them “We are actively shaping our entire semiconductor supply chain,” says VW’s Murat Aksel, “we’re ensuring the production of the exact chips we need for our cars and securing the supply of critical microchips for years to come.” ...

The market for automotive SiC power components is forecast to reach $1.07 billion in 2022 and will climb to $3.94 billion by 2026, says TrendForce, in a total SiC device market estimated by Yole Developpement to be worth $6.3 billion in 2027. The leading suppliers are: ST ON Wolfspeed, Infineon China is operating an entire SiC industry supply chain. Car ...

With global demand for EVs growing at pace, the race is on for battery innovators to avert a supply crisis due to shortages of various elements found in the earth’s crust, such as nickel, cobalt and lithium, writes Ben Palmer, a partner and patent attorney at Withers & Rogers. Diminished availability of these much-needed raw materials, combined with growing concern ...
