Texas Instruments today introduced a bidirectional isolator family compatible with I2C interfaces that consumes as much as 38-percent lower power than competitive devices. Each of the new integrated circuits can replace a typical implementation of 16 or more discrete devices to isolate the I2C signal in industrial applications.

Avago Technologies today announced its ACPL-M49U/K49U/M71U/M72U digital optocouplers, which are new additions to its R2CouplerTM family. These optocouplers provide a wider offering of extended temperaturerange digital optocouplers to the exisiting family and are designed to meetcustomer needs for low power, low leakage, higher isolation voltage and higher common-mode rejection (CMR).

Akros Silicon have recently announced an interoperability collaboration with Broadcom to provide fully integrated support of the emerging Power over Ethernet 60 Watt extension. Broadcom has a family of PoE Power Sourcing Equipment controllers (model BCM59111) that supports the rapidly emerging 60W application requirements.

Akros Silicon announces the immediate availability of the AS1860, the newest member of the company’s GreenEdge family of system-on-a-chip energy management ICs. The AS1860, equipped with Akros’ proprietary GreenEdge digital isolation technology, is uniquely suited to support deployments of 60W and above Power over Ethernet Powered Device applications such as thin clients, monitors, industrial Ethernet, IPTV, building management, Industrial Ne...

Analog Devices today introduced the industry’s smallest isolated DC-to-DC converters. The ADuM5010, ADuM6010, ADuM521x and ADuM621x use ADI’s proprietary isoPower isolated DC-to-DC converter technology to deliver 150 mW of output power while using less board space than competing module-based solutions. The ADuM521x and ADuM621x also integrate two channels of ADI’s award winning iCoupler data isolation technology to reduce board ...

Silicon Laboratories Inc today introduced the industry’s first drop-in replacement for optocouplers based on mainstream CMOS technology and incorporating an innovative light-emitting diode (LED) emulator input. The new Si87xx digital isolators offer a perfect pin configuration, package and footprint fit for a number of optocoupler products while offering superior noise immunity, more robust performance and greater reliability, making them ideal...

Vishay Intertechnology, Inc is broadening its optoelectronics portfolio with the release of a new series of low input current optocouplers with phototransistor output. The VOM617A and VOM618A series feature low input currents of 1 mA (VOM618A) and 5 mA (VOM617A) in the compact SOP-4 mini-flat package, which saves 30 % PCB space over the DIP-4 package.

High-power industrial applications such as solar power inverters, motor drives and uninterruptible power supplies (UPS) demand a gate driver optocoupler with high performance and critical protection features. Fairchild Semiconductor developed the FOD8316 smart gate driver optocoupler, an advanced 2.5A output current IGBT drive optocoupler to help designers meet this challenge.

Texas Instruments Incorporated today introduced an isolated gate driver for insulated-gate bipolar transistors (IGBTs) and MOSFETs that is 40 percent faster than equivalent optical gate drivers. The input TTL logic and output power stage in the ISO5500 are separated by a capacitive, silicon dioxide (SiO2) isolation barrier that doubles the lifetime of the device compared to optocouplers and magnetic isolators. When used with isolated power suppli...

The traditional way of implementing a fully isolated 2-channel RS-232 interface is to use optocouplers to provide data isolation of the RS-232 link. One optocoupler is needed for each data line (TIN1, TIN2, ROUT1, ROUT2), along with an external buffer for each one.
