2.5A 5kV isolated gate driver is just 2.3mm high, with 8mm creepage

Toshiba’s TLP5832 gate driver photo-coupler delivers 2.5A peak output current from an SO8L package only 2.3mm high – approximately 50% lower than the firm’s current SDIP6 and DIP8 packages. “In spite of its small size, the IC offers an isolation voltage [BVS] of 5,000Vrms and guarantees creepage and clearance distances of minimum 8.0mm, making it suitable for applications ...

Large hadron collider beams – made in Switzerland, monitored by Germans

Over 140 digitiser cards from Spectrum Instrumentation are being used to protection systems in the Large Hadron Collider (LHC) at CERN. The needle-like particle beams within the LHC contain huge amounts of energy – 350MJ, about as much as the Flying Scotsman at full speed – and cannot simply be turned off. Instead, each is ...

UHF harvester powers retail tag over 2m gap

US energy harvesting firm Powercast has developed a battery-free retail price tag that can be changed from 2m away using a hand-held UHF programmer. Key to the tag is the firm’s PCC110 UHF-to-dc harvestign chip and an Eink display that only needs power to change, retaining its display after power is removed. “Powercast developed the ...

Brushed motor driver handles up to 50V 9A

Toshiba has created a motor driver for brushed electric motors used in, for example, domestic robotic vacuum cleaners, banking terminals and cash dispensers. Called TB67H420FTG, it can separately control two 47V (10Vmin, 24Vnominal) motors running at up to 4.5A, or via a separate mode the bridges can be combined to power a single 47V 9A motor. The ...
