Diodes has used post-package trimming to hone a 25μV maximum offset 9.5nV√Hz (1kHz) noise dual op amp with 5.5MHz bandwidth. Called AS2376Q, the device is intended for filtering and control, particularly in automotive applications – it is qualified AEC-Q100 Grade 1 and has automotive-grade supporting PPAPs. Both input and output are rail-to-rail, and operation is over 2.2 to 5.5V (950μA ...

Onsemi has announced three silicon carbide power modules for 800V 11 – 22kW on-board charging and high-voltage dc-dc converiosn in electric vehicles  – all in transfer moulded packaging, claimed to be a first. “Our modules employ the latest SiC technology to minimise losses and overall system volume, allowing designers to meet charging efficiency and space goals,”, claimed Onsemi general manager ...

The automotive IC matketshare will be 10% by 2026, says IC Insights, posting average annual growth of 13.4% from 2021-26. The communications and computer segments will remain the largest applications. Figure 1 shows that the automotive IC marketshare has steadily increased since 1998 growing from 4.7% of total IC sales that year to 7.4% in 2021. Marketshare gains are forecast ...

STMicroelectronics has used the ‘CAN FD Light’ protocol in a 32-channel automotive lighting controller. “With 32 regulated current sources, independently programmable from 1mA to 15mA, L99LDLH32 can drive individual pixels in external and interior lighting applications. Global dimming is also provided, with 8-bit resolution,” according to the company, whose data sheet said that it is particularly aimed at external rear ...

Rohm has developed a buck dc-dc converter for driver assistance (ADAS) and automotive infotainment systems. BD9S402MUF-C operates at 2MHz and can deliver 4A at outputs down to 0.6V. Load response is fast: “The ability to suppress voltage output variation within 5% even at output voltages below 1.0V makes it ideal for secondary power supplies for the latest ADAS”, according to ...

Alps Alpine is aiming at safety redundancy, particularly in vehicle power steering, with a pair of magnetic angle sensors on two separate die inside the same package, positioned to share the same external magnet. “Redundancy design is increasingly a requirement for automobile driving systems,” according to the company. “The use of multiple sensors was once the typical way of realising ...

Durable and secure connections for industrial and automotive applications. Signal connectors from the 140 series Waterproof E-Seal connectors Edge connectors All kinds of electronic equipment need the right kind of connections in order to operate properly. Thanks to them it is possible to supply power to a particular module or send information between two printed circuits. We can connect an ...

Harwin has added male flying leas options to its Kona high-power compact connector range, rated at 1.5kV and 60A per contact. All the new parts are suited to 8AWG wire. “This addition makes it possible to bring male and female cables together for the first time in a cable-to-cable arrangement, whereas previously we were only offering Kona in cable-to-board options,” ...

Reliable, Convenient Fast Charging Will Drive the Future of EV Adoption For consumers in developed nations, lifestyle convenience is ingrained. We don’t know what it’s like not to have access to necessities – food, water, clothing, housing and transportation – not to mention luxuries. When it comes to dependency on automotive transportation that, too, is built on confidence around readily-available ...

Microchip is aiming to meet ISO 26262 functional safety and new ISO/SAE 21434 cybersecurity standards with a family of Arm Cortex-M0+ microcontrollers with memory-built-in self-test, secure boot and support for Autosar – the latter an open software architecture that allows lower-level hardware to be changed without changing the original application code. “When using Autosar, Microchip offers ASIL B microcontroller abstraction ...
