Infineon is aiming at 48V automotive applications with AUCN08S7N013, an 80V mosfet in a 5 x 6mm SSO8 that has a maximum on-resistance of 1.3mΩ at 25°C (Tj, 10Vgs, 88A Id). “48V applications including electric power steering, braking systems, power switches in zone architectures, battery management, e-fuse boxes, dc-dc and brushless dc motor drives,” it said. The mosfet is several ...

Novosense Microelectronics announced a 24 channel automotive LED driver at PCIM in Nuremberg today. NSL21924 is a high-side driver, aimed at rear lights, exterior lights and general automotive interior and body lighting. 16 channel NSL21916 is also available. Qualification is to AEC-Q100 Grade 1 (Tj = -40 to +150°C). The LED supply voltage can be across 3 to 16V, and ...

Applied EV has picked Cissoid to supply silicon carbide based inverter modules for its autonomous electric vehicles. The module, CXT-ICM3SA, was introduced at APEC earlier this year and combines a three-phase 1.2kV SiC mosfet bridge – rated at 340 to 550A depending on model – a driver board and a control board in a stack. The control board is built ...

Microchip has turned to silicon carbide to create a bi-directional electric vehicle on-board charger design for 400V or 800V batteries. There are two halves: a 7.6kW bi-directional two-phase interleaved totem-pole power factor corrector, and an 11kW dual full bridge transformer-coupled bi-directional dc-dc converter. “These two designs work together,” Microchip told Electronics Weekly. “At PCIM we showed both operating in bi-directional ...

The worldwide automotive semiconductor market revenue will have a 7% CAGR from 2023-27 to reach $8.5 billion, according to IDC. “Among the multiple use cases, the segments of smart cockpits and autonomous driving have experienced the most rapid growth, with forecasts showing that they are poised to secure over 50% of the market share by 2027,” says IDC research director ...

Asahi Kasei Microdevices (AKM) and Silicon Austria Labs (SAL), have conducted a joint proof of concept for eFuse technology in high-voltage applications using SiC-based power devices. The results show that eFuse technology can significantly improve safety and reduce the material and maintenance costs of systems such as on-board chargers (OBC) in motor vehicles. SiC and GaN-based power electronics are increasingly ...

Volvo Trucks is developing trucks with combustion engines that run on hydrogen. On-road tests with trucks using hydrogen in combustion engines will begin in 2026, and the commercial launch is planned towards the end of this decade. Trucks that run on green hydrogen provide a significant step for Volvo to achieve its net zero goal and support customers in reaching ...

ROHM and Nanjing SemiDrive have jointly developed a smart cockpit reference design. The design is primarily based on SemiDrive’s X9M and X9E automotive SoCs, and includes PMICs, SerDes ICs, LED driver IC, and other components from ROHM. A reference board based on this design is also available, consisting of three boards: the CoreBoard, the SerDes Board, and the Display Board. ...

FCL Components has announced a 60A 400Vdc relay for PCB-mount automotive applications that does not need a reduction in coil voltage after actuation. Called FTR-E1-HC, its coil only dissipates ~1.2W at rated voltage. Dielectric strength is 5kVac (1 minute) between coil and contacts, and 2.5kVac between contacts. “The FTR-E1-HC also features arc extinguishing technology which use a cleverly placed permanent ...

Drive System Design (DSD) and Alvier Mechatronics have teamed up to create a development platform for electric vehicle drives. “The project leverages DSD’s expertise in rapid development engineering and Alvier Mechatronics’ experience in novel manufacturing methods for high-volume applications, material know-how and electromagnetic design,” according to DSD. Called iDS, it “showcases technologies, materials and analysis techniques with real, tested hardware for ...
