TDK is aiming at automotive and industrial 360° magnetic angle sensing in high-reliability systems with a tunnel-magnetoresistance (TMR) IC. TAS8240 is designed to operate next to a rotating magnet and contains four pairs of TMR half bridges (four Wheatstone bridges) to provide four separated sine-cosine outputs. “Depending on system architectures, fail-operational concepts can be supported by the new sensor,” according ...

Renesas and partners have collected together hardware, operating systems, software and design tools needed to develop the electronics in a software-defined vehicle. Branded ‘R-Car Open Access’ and ‘RoX’, with it “engineers can start building their software using an integrated tool chain even before the hardware is available”, according to Renesas. “This is made possible through the cloud environment and the ...

The Blackwell architecture took pole position at this year’s Nvidia GTC in California. Caroline Hayes looks at its role in Drive Thor in-vehicle computing in some of the latest models on our roads. Drive Thor targets the 2025 production models, in which more automated and assisted driving will be included. It is Nvidia’s latest in-vehicle computing platform and the successor ...

Samsung has created a 630V 100nF multi-layer ceramic capacitor in 1210 size (3.2 x 2.5mm) specifically for electric vehicle dc-dc converters and on-board chargers. CL32B104KHU6PN has an X7R dielectric (±15% capacitance -55 to +125°C) and a maximum rated voltage of 630V. “A dc-dc converter converts high voltages to 12Vdc in order to operate in-vehicle infotainment systems, for example,” according to ...

STMicroelectronics has added I2T fusing to a automotive quad high-side power switch. As well as current-squared time fusing VNF9Q20F, as it will be known “responds within 100µs to turn off the [output] mosfet if excessive current is detected”, said ST. “Performing as an intelligent circuit breaker, [it] enhances board-net voltage stability and prevents PCB traces, connectors and wire harnesses from ...

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) ...
