Two new industrial communications products from Brainboxes will be on the Farnell stand at the National Manufacturing Supply Chain Exhibition in Dublin. PE-505 is a 55 x 55 x 10mm five-port 10 and 100Mbit/s (10BASE-T/100BASE-T) isolated (1.5kV) Ethernet switch PCB with non-blocking layer 2 operation, that can be built into equipment. Operation is from 3.3V (1.3W) or 4.5 – 12V ...

P-Duke has announced ultra-wide input isolated 40W dc-dc converters for railway and industrial use. RED40-72xxxU converter will work over 14 – 160Vdc (11:1 range) and comes in a 2 x 1in (~25 x 50mm) footprint package. “Using just one dc-dc converter model for various supply voltages – 24, 28, 36, 48, 72, 96 or 110Vdc – in different regions avoids ...

Arron Bickerton, of TTI Europe, observes two trends in the sensor marketplace. The first is supplier consolidation and the second is the rise of digitisation. Over the past five years, many suppliers have acquired disparate types of sensor companies and are now consolidating technologies and narrowing their portfolios. As a result, certain parts are now being made obsolete or are ...

Collaboration is a continuing industry trend, and open source communities are broadening access. Caroline Hayes reports on an automotive initiative for software defined vehicles. At this year’s Embedded World Europe, the OpenHW Group and the Eclipse Foundation confirmed their joint intention to develop a robust ecosystem for development tools, using Eclipse integrated development environments (IDE). OpenHW’s Rick O’Conor and Eclipse’s ...

EPC is aiming at eMobility, forklifts and high-power drones with a 150Arms brushless motor driver design using its GaN power transistors. Documents for EPC9186, as it will be known, are not available yet, but the company promises operation from 14V to 80V for “applications such as electric scooters, small electric vehicles and agricultural machinery” in addition to the items above. ...

Texas Instruments is aiming at electric vehicle traction inverters with a functional safety-compliant isolated gate driver for silicon carbide mosfets and IGBTs. Called UCC5880-Q1, it is in pre-production and the full data sheet has not yet been made public. One novel feature that has been revealed is that the device has two parallel high-side drivers and two parallel low-side drivers ...

Melexis is encouraging innovation and drawing on the rich pool of local technology graduates at its newly-opened Innovation Lab. Positioned in the Swiss canton of Neuchâtel, the Melexis Innovation Lab is the latest addition to the Belgian company’s site in Bevaix, near Geneva. The lab was opened in December 2022 and is a centre for pre-development of sensor technology products ...

Infineon  is in volume production of its  OptiMOS 7 40V MOSFET family for automotive applications and they can be ordered in August. They combine 300 mm thin-wafer technology with innovative packaging and are  suitable for standard and future automotive 40V MOSFET applications, such as electric power steering, braking systems, disconnect switches new zone architectures. OptiMOS 7 is also aiming at ...

Premo has released a four-phase toroidal common-mode choke for EMC noise suppression in electric vehicle on-board chargers up to 22kW. 4CMCN065R0-32H measures 59mm in diameter, 41.5mm (plus pins) high and ~200g, and is nominally rated at 32A. All the windings have the same number of turns (8), but the one intended for the neutral of a three-phase mains circuit is ...

STMicroelectronics has introduced automotive-qualified MEMS six-axis inertial-sensing module. ASM330LHB, as it will be known, contains a 3-axis accelerometer and 3-axis gyroscope, and is AEC-Q100 qualified. Used in pairs for fail-safe redundancy, with dedicated companion software, it can be used in functional-safety applications up to ASIL B. “Developed in accordance with the automotive functional-safety standard ISO 26262, the software library has ...
