Micronas had created a pair of automotive-rated Hall effect magnetic angle sensors that work up to 150,000rpm. “Developers have the choice between two sensor models – HAL 3020 and HAL 3021 – for fast angle determination, with which they can meet the need for robust motor position detection and ISO 26262-compliant development. The components have differential or single-ended sine and ...

Melexis has extended its LIN RGB automotive LED driver offering with the MLX81123 offering cost-effective performance and reliability in a small package. Ambient LED lighting is now a key design feature for automotive manufacturers, enhancing the end-user’s experience and helping OEMs to provide striking visual distinction. With well known OEMs utilising ambient lighting extensively across their latest models, maintaining a ...

A two-chip cascading imaging radar system has been unveiled by Calterah, based on 6T-6R mmWave radar SoCs from Andes Technology. The 22nm CMOS SoCs, which will be available from June 2024, integrate an RF module and include a quad-core CPU with a DSP and proprietary radar signal processor. Flex-Cascading allows the two SoCs to be cascaded through chip-to-chip interfaces. This ...

In the context of the explosive growth of the energy storage market. New energy storage market prospects With the increasing penetration of renewable energy, especially due to the instability of wind and solar power, the role of energy storage systems in balancing grid supply and demand and mitigating fluctuations is becoming increasingly evident. Additionally, the development of the electric vehicle ...

To meet low-power and high-performance requirements, system on chip (SoC) designs are equipped with several asynchronous and soft reset signals. These reset signals help to safeguard software and hardware functional safety as they can be asserted to speedily recover the system onboard to an initial state and clear any pending errors or events. By definition, a reset domain crossing (RDC) ...

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 ...
