Diodes has announced its API772x RobustISO products, a series of dual-channel digital isolators. Suggested applications – for digital signals in critical applications – include industrial automation, energy power systems, and data center power supplies. RobustISO The RobustISO digital isolators meet reinforced and basic isolation requirements across various standards, including VDE, UL, and CQC. They offer a 5,000VRMS isolation rating for ...

Toshiba is sampling a gate driver IC designed to control high-current brushed DC motors. Applications include powered tailgates, sliding doors and seat adjusters. In addition to the optionally available standard PWM input pins, the TB9104FTG  gate driver IC features an intelligent serial peripheral interface (SPI) for controlling the motor operation itself. Several motors can be controlled using just the SPI ...

Last month, Kyocera and Maxell started running test operations installing power modules using Maxell’s all‑solid‑state battery “PSB401010H” in industrial robots and controllers at Kyocera’s Kagoshima Sendai Plant, one of its semiconductor ceramic package production sites. The ceramic‑packaged all‑solid‑state batteries produced by Maxell feature high reliability, and their exterior housings adopt ceramic packages manufactured by Kyocera. With superior heat resistance and ...

Providing power in extreme environmental conditions, in particular oil and gas applications, drilling or pipeline inspection, Ultralife has developed the SeaSafe Endurance battery module. It is, said the company an easy-to-configure battery system designed to fit inside pressure vessels. If required, two batteries can be placed on top of each other or a battery can be placed in an adjacent ...

University College Birmingham (UCB) is celebrating the first cohorts of students through both its Advanced High Voltage (HV) Battery Assembly and Gigafactory Operations courses. Specifically, attendees from Jaguar Land Rover, Atlas Copco and Autocraft graduated from a dedicated learning facility within the UCB. The five day courses are described by the university as the first, fully accredited, advanced battery courses ...

Toshiba has integrated its SmartMCD for dual brushed DC motors into the Mikroe’s SmartMCD TB9M001FTG board. The board enables automotive system engineers to design the TB9M001FTG smart motor control driver for automotive applications, including electric sunroofs, wipers, powered windows, and adjustable seats, to streamline the prototyping phase. The AEC-Q100 (Grade 1) qualified SmartMCD device meets ASIL-A requirements. It includes built-in ...

ST’s SRK1004 synchronous-rectifier controllers save space and increase efficiency in the secondary side of active-clamp, resonant, and quasi-resonant flyback (ACF, AHB, QR) converters for chargers, power adapters, and switched-mode power supplies. The 2mm x 2mm ICs supersede the SRK1001 and implement a new switch-off algorithm for increased efficiency and robustness. With six variants available, the SRK1004 series lets designers choose ...

Toshiba is expanding its surge protection Zener diodes lineup with the addition of four new products to its CUZ series. The CUZ56V, CUZ62V, CUZ68V, and CUZ75V, with Zener voltages (VZ) of 56V, 62V, 68V, and 75V respectively, are designed for use in power supplies for data centers, network equipment, industrial systems, and system architectures with 48V and above. The new ...

Allegro MicroSystems has created a pair of ICs that transmit isolated control signals and power to silicon carbide mosfet gates. AHV85003 is the transmitter and AHV85043 is the receiver, which need to be connected together through an isolation transformer. “With selectable gate-to-source voltages of 15V, 18V and 20V, and adjustable regulated negative voltage, designers can swap between SiC FETs from ...

Finnish company Enedo Power has turned to GaN transistors to put a 1,200W ac-dc power supply into a 41 x 107 x 206mm (900cm3) volume. Called HDP1200, they run from 85 – 305Vac (de-rated to 1kW below 137Vac) and produce 24V or 48V depending on type, plus a 5V 1.5A stand-by output. Efficiency is up to 95.5%, and a fan ...
