Stackpole is offering 0.01% 2ppm/°C precision surface-mount resistors in sizes from 0402 to 2512 (1 x 0.5mm to 6.3 x 3.1mm). Part of its RNCF range, these highest spec parts don’t come in the wide value range of lesser RNCF resistors. For example: 0402 types are available between 49.9Ω and 4.99kΩ, then 2512 has the widest span of options,  between ...

Motor inverter maker Vitesco Technologies has signed a silicon carbide component supply deal with Rohm “worth over one billion US dollars until 2030”, according to the companies. This fruit was born of a development partnership started in 2020, leading to two unnamed automotive customers adopting Vitesco inverters built around Rohm SiC components, with “Vitesco supplying a first series project as ...

Diodes has created a series of automotive-compliant PCI Express 3.0 packet switches for in-vehicle networking. “The architecture used enables flexible port configuration with upstream, downstream and CDEP [cross-domain end-point] ports being assigned according to requirements,” according to the company. “They can connect with up to seven different endpoints and support multi-host applications.” PI7C9X3G606GPQ offers 6-port/6-lane operation, PI7C9X3G808GPQ 8-port/8-lane and PI7C9X3G816GPQ ...

Infineon has used its latest silicon carbide die technology in a 1,200V mosfet for automotive on-board chargers and dc-dc converters. The snappily-named AIMBG120R010M1 comes in a 10 x 15 x 4.4mm D2PAK-7L (7 lead TO263) package and handles 1.2kV across -55 to 175°C. Creepage is 5.89mm, suiting the device to 800V systems. Its ‘Gen1p’ process has been created to improved ...

Belgian lab Imec is claiming record ranging precision and power consumption for a novel 6 – 9GHz IEEE 802.15.4z UWB (ultra-wide-band) impulse-radio transceiver: 1.4mm ranging, and 8.7mW Tx plus 21mW Rx consumption in continuous mode. “It paves the way for a variety of automotive applications,” according to Imec. “One use-case includes the creation of radar-on-chip systems for in-cabin child presence ...

Faced with an empty driving seat, pedestrians trust certain visual prompts when deciding whether to cross in front of an autonomous car, according to the University of Nottingham, which has studied such behaviour on its own campus. The study used a fake autonomous car, with a concealed human driver, equipped with animated display panels on its front that pedestrians could ...

Renesas Electronics has teamed up with electric motor maker Nidec to develop a 6-in-1 e-axle for electric vehicles. E-axles combine motor, inverter and gearbox into one unit and, according to Renesas, are beginning to collect other power electronics functions such as dc-dc converters and on-board chargers to form a convenient package for car makers to integrate – an idea dubbed ...

Recom is aiming at railway use with a family of DIP24 isolated regulated dc-dc converters that will run from between 36 and 160Vdc. Surges up to 200V can be tolerated for 1s. “Dc-dc for rail applications typically operate from 72V, 96V, or 110VDC nominal input with dips and surges,” according to the company. There are 10W (RP10-RAW), 6W (RP06-RAW) and 3W ...

AMD is aiming at automotive edge sensor fusion, for the likes of lidar, radar and 3D surround cameras, with a pair of FPGAs it has just started shipping. XA AU10P and XA AU15P are automotive-qualified, certified for functional safety up to ASIL-B, intended to be used in driver assistance systems, and come with the the company’s Artix UltraScale+ branding. The ...

Analog Devices has created a pair of 6A buck-boost converters for automotive use. “MAX25239 and MAX25240 small-footprint 2V to 36V converters are the industry’s only 6A automotive buck-boost with integrated H-bridge switches,” according to distributor Farnell, which is stocking the parts. “They provide a fixed-output regulation voltage and an externally adjustable output voltage from 3V to 20V.” The ‘and’ in ...
