Last month, government funding body UK Research and Innovation revealed the winners in its £22m Supply Chains for Net Zero Competition – announced in March 2021 and focused on supply chain development for power electronics, electric machines and drives (PEMD). “The coming electric revolution presents an opportunity to put the UK at the forefront of a burgeoning industry, creating manufacturing jobs and ...
Allegro MicroSystems has released two automotive magnetic sensors, one for crankshafts and one for camshafts, both using the giant magnetoresistance (GMR) effect. Although both come in a simple three-pin single in-line package, they are sophisticated digital processing ICs, and system-in-packages as they also incorporate a bias magnet and EMC protection components. Crankshaft The ATS16951 crankshaft sensor is designed to be a ...
Power over Ethernet (PoE) is rapidly gaining market share, in some rather unexpected places, writes Philip Lechner of Avnet Abacus. In fact, for a technology with relatively humble origins, PoE is shaping up very well indeed. A recent report from ResearchAndMarkets.com predicts that the global market for Power Over Ethernet (PoE) Solutions will reach $1.1 Billion by 2025, hitting a 10.8% ...
Alpha and Omega Semiconductor is aiming at servers with a pair of 600V super-junction mosfets in 8 x 8 x 0.9mm DFN8x8 packaging, with a Kelvin source. AONV110A60 has 110mΩ on-resistance, and AONV140A60 has 140mΩ. “Years ago, we could hardly imagine high voltage DFN8x8 devices widely adopted for server systems above 400W. People used packages such as TO-220(F) or D2PAK. Given the large ...
Different components affect system accuracy. Shaury Anand, of Texas Instruments, explains how to choose those most suitable for a precision DC power supply design. Test and measurement applications such as battery test, electrochemical impedance spectroscopy and semiconductor test require accurate current and voltage output DC power supplies. Both the current and voltage control accuracy of the equipment need to be better ...
Optimizing first for best power instead of best timing delivers better results all around. Among the key targets in place-and-route—performance, power, and area (PPA) — performance has traditionally been the primary focus. Low power has been gaining in importance though, particularly at today’s advanced process nodes. Of course, no one wants lower-performing chips, so place-and-route tools employ a variety of ...
TDK-Lambda has extended its CCG series of dc-dc converters further downward with the introduction of 3W and 1.5W models – in 2015 there were 30W CCG converters, reaching 15W the next year. The two new types have a lot in common. Firstly, they share a 15.7 x 10.4 x 11.5mm plastic case, with through-hole or surface-mount terminations (see photo). “On the ...
Digi-Key Electronics, in collaboration with Siemens, will host an online webinar about power reliability for automation and control systems. It takes place on Tuesday, 8 March, at 11 a.m. (CST) and will be presented by Greg Kateb, SITOP power product consultant for Siemens. Spcifically, Kateb will address a variety of scenarios that a power system might face, such as short ...
Infineon has created a family of single-channel isolated gate driver for IGBTs and silicon carbide mosfets with up to 300kV/μs common-mode transient immunity and up to +6 and -8.5 A typical peak current. Called 1ED332x, and branded ‘F3 Enhanced’, they come in 300mil wide DSO 16 packaging with 8mm creepage distance. Operation is expected with devices between 600V and 2.3kV – ...
Diodes has announced an ideal diode controller for reverse discharge protection. Called DZDH0401DW, it is designed to work with a p-channel mosfet in the high-side rail in systems up to 40V. It might better be described as a ‘nearly ideal diode controller’ as it draws some current from the output circuit when no input is connected – 147μA if a ...
