Battery monitor for non-rechargeable cells charges supercapacitors too

Analog Devices has created a battery monitor for primary (non-rechargeable) cells that counts coulombs and can handle a pair of output supercapacitors. Called LTC3337, “the patented infinite dynamic range coulomb counter tallies all accumulated battery discharge,” boldly claimed ADI, Coulomb counter accuracy is constant down to no load.” However, Coulomb counting accuracy, according to the data ...

Arm Soafee: Web-native development for automotive functional safety

Arm has got together with the automotive supply chain to create a web-native development environment for functional safety and real-time software. To be called Soafee, for Scalable Open Architecture for Embedded Edge, it is the result of automakers, system integrators, semiconductor, software, and cloud technology companies coming together to define an open-standards-based architecture for the ...

Peering into the finer details of hydrogen fuel cells for trucks and busses

Fuel cell control systems will need to be highly sophisticated if the technology is going to find its way into transport, according to German hydrogen and fuel cell research centre ZBT, which is developing it for trucks and busses. In hydrogen fuel cells, hydrogen is fed to the anode while air is fed to the ...

6mΩ 750V SiC FET from UnitedSiC 

A 6mΩ 750V SiC transistor is amongst nine devices announced by UnitedSiC. The company decribes the transistors as ‘FETs’, although each is a co-packaged cascode pair of a depletion-mode high-voltage SiC JFET and a low-voltage silicon mosfet. “At a Rds(on) of less than half the nearest SiC mosfet competitor, the 6mΩ device also provides a short-circuit ...

Arduino strips video fromn Portenta H7 for lower cost industrial IoT

Arduino is offering a stripped-down version of its high-end Portenta H7 computer board, without the video output, with one secure element rather than two, and with no Bluetooth or Wi-Fi. Called Portenta H7 Lite and part of the organisation’s ArduinoPro industrial IoT family, it sees it being used in AI applications and low-latency control projects “for ...
