Infineon has added gate drive charge pumps to keep motor drive mosfets working properly in a three-phase motor controller that works across 5.5 to 60V, and up to 1.5A (diagram below). Called 6EDL7141, it can drive gates from 7, 10, 12 or 15V, provided by one charge pump for the low-side mosfets and one for ...

Toshiba has updated its solid-state lidar, claiming the world’s smallest physical volume. A key improvement is within the silicon photo-multiplier (SiPM) light receiving integrated circuits which have light-receiving cells controlled by transistors. The new chips have smaller transistor modules, replace buffer layers protecting the transistors with newly-developed insulating trenches between the transistors and the light-receiving ...

Chinese scientists have revealed details of Queqiao, the lunar communications satellite that relays data between the Chang’e-4 moon lander and Earth. Needed because the lander is on a part of the Moon which does not have direct line-of-sight with the Earth, Queqiao has been placed in orbit around the second Lagrange point in the Earth-Moon system. ...

Fluke has introduced a cable and network tester for installers and maintenance technicians. Called LinkIQ Cable+Network, it makes frequency-based cable measurement and shows the maximum data rate the cable can support, up to 10Gbit/s. It also displays information on the cable distance-to-fault and, if connected, details of the nearest switch port, including its name, VLAN ...
