Avago Technologies today unveiled two new sets of high speed gate drive optocoupler devices, the ACPL-P/W345 and ACPL-P/W346. These devices are 1A and 2.5A gate drive optocouplers designed to protect and drive Power MOSFET and Silicon Carbide (SiC) MOSFET for high switching frequency applications such as inverter, motor control, and switching power supply (SPS). Compared to Avago’s previous generation devices, the ACPL-P/W345 and ACPL-P/W346 ar...

Safety, security and ultra-low power were the overriding themes of this year’s Embedded World Exhibition and Conference, which took place to great success between February 25th to 27th in Nürnberg, Germany. Philip Ling reports for ES Design magazine.

In this article from ES Design Magazine, John Mossman, Control & Automation Marketing Manager for Maxim Integrated and a member of Maxim’s strategic marketing team, takes an in-depth look at how self-monitoring ICs can help industrial facilities keep running at maximum capacity 24 hours a day, 365 days a year.

Designers working with industrial applications need to transmit high speed data reliably in environments where noise – in the form of voltage transients and ground loop currents – is common. They also need to meet stringent new safety standards, such as IEC-62109, the international standard for solar inverters. At the same time, designers need solutions that are flexible, and that take up less board space while reducing bill of material costs...

IXYS announce the immediate availability of the PLA192E and PLA193E, 600V, single-pole, normally open (1-Form-A) Solid State Relays with 150mA and 100mA load current ratings, respectively. These devices use an exclusive patented optically coupled photovoltaic technology and efficient MOSFET output switches to provide an enhanced input-to-output isolation of 5000Vrms.

Vishay Intertechnology, Inc is broadening its optoelectronics portfolio with the release of two new series of 4-pin, low input current optocouplers with phototransistor output. The devices feature low DC input currents of 1 mA (VOS618A) and 5 mA (VOS617A) and are offered in the compact SSOP-4 mini-flat package, which saves more than 60 % of board space compared with a DIP-4 package.

Analog Devices, Inc. have today announced the release of new isolated error amplifiers that provide power supply designers with a higher performing, single-chip alternative to isolation techniques based on optocouplers and shunt regulators. Designed for linear feedback power supplies using primary side controllers, the ADuM3190 and ADuM4190 isolated error amplifiers have a 400-kHz bandwidth, with 0.5% typical initial accuracy at 25°C and 1% tota...

Linear Technology Corporation announces the LTC3300-1, a high efficiency bidirectional multicell battery balancer for equalizing cell state of charge (SoC) in a series-connected battery stack. With the LTC3300-1, applications such as electric vehicles (EVs), plug-in hybrid EVs and large energy storage systems using cells with mismatched capacities are no longer limited by the lowest capacity cell in the stack. The LTC3300-1 goes beyond purely dis...

For today’s high-power industrial applications, designers have traditionally used discrete components for the IGBT drivers, resulting in higher overall design complexity and increased system costs. To help designers overcome this, Fairchild Semiconductor has launched the FOD8318 Smart Gate Driver Optocoupler with Active Miller Clamp. The device is an advanced 2.5A output current IGBT drive optocoupler capable of driving most 1200V / 150A IGBTs.

NVE has introduced narrow-body versions of its award-winning IsoLoop IL3585 and IL3685 RS-485 and PROFIBUS-compliant high-speed isolated transceivers. The narrow-body versions, designated with the -3E suffix, are the world’s smallest isolated transceivers. The “dash 3” 0.15-inch wide, 1.8 millimeter clearance height 16-pin SOIC package is half the size of other isolators.
