Renesas announced the development of an optical-coupled metal-oxide-semiconductor field-effect transistor (MOSFET), the PS7901D-1A, that achieves complete electrical isolation within the package by using light for signal transmission.

Avago Technologies have announced a new generation of gate drive optocouplers that deliver industry-leading performance from a small-footprint package. The new ACPL-P34x and ACPL-W34x optocoupler family is based on process technology that enables higher output current drive with rail-to-rail capability, providing high-voltage insulation and robust protection for industrial drive, inverter and power supply applications. The optocouplers are availa...

Vishay is broadening its optoelectronics portfolio with the release of two high-speed analog optocouplers in the industry-standard SOP-5 package, saving up to 75 % in PCB space compared to a DIP-8 SMD package. The new VOM452T and VOM453T feature a baud rate of 1 MBd in a low-profile package with a height of 2.0 mm. They also feature a very short propagation delay of 1 µs which is critical for applications requiring faster switching times than s...

Avago Technologies announced that Yaskawa Electric Corporation has selected two of its latest R2Coupler™ isolation products for use in the futuristic Mazda Premacy hydrogen/gas powered hybrid vehicle. Yaskawa, which makes the electronic motor inverter system for the Premacy, is using Avago’s ACPL-782T automotive grade isolation amplifier and ACPL-312T gate drive optocoupler in its electronic motors.

Linear Technology announces the LTC6801, a high voltage battery stack fault monitor that operates without a microprocessor, and without the need for optocouplers or isolators. An LTC6801 can monitor up to 12 series-connected battery cells for overvoltage and undervoltage conditions. Multiple LTC6801 devices can be daisy chained, providing a method to monitor each individual cell in very long battery strings. When connected in a daisy-chain, a sin...

NEC Electronics has introduced the first product in a new series of IGBT/MOSFET gate drive optocouplers. The PS9552 consists of a GaAlAs LED on the input side and a photo diode with signal processing circuit and power stage on the output side. It is a combination of a fast optocoupler providing galvanic isolation and an IGBT/MOSFET driver supplying high output voltage and current. The design features common mode transient immunity of at least 15 ...

NEC Electronics introduces a new family of High Speed Optocouplers coming in a new white DIP package that provides enhanced isolation and shielding characteristics: 5000 Vrms isolation voltage; >0.4mm internal isolation distance; >8mm outer creepage distance; Minimum CMR of 15KV/µs.

NEC Electronics Europe has introduced new transistor output optocouplers with guaranteed operation up to 110degC ambient temperature. The extended temperature range make them ideal for applications such as switched mode power supplies and factory equipment, and all applications where components are packed densely.

This presentation, provided by Digi-Key and Analog Devices, will discuss the proprietary iCoupler® transformer isolation technology and how it addresses the limitations of optocouplers.

Vishay Intertechnology has announced two new controller ICs for intermediate bus converter (IBC) applications that are the first such single-chip devices on the market to integrate high-voltage (75-V) half-bridge MOSFET drivers with a 1.6-A peak current driving capability, as well as a full range of current monitoring and control features.
