Analog Devices has expanded its broad portfolio of digital isolation products with a family of four-channel devices that meet stringent medical-grade specifications for data and power isolation in patient monitoring and other medical equipment. Each device integrates ADI’s iCoupler digital isolation technology and proprietary isoPower dc-to-dc converter, providing both isolated power and isolated signal channels within a single package.

The growing popularity of electric and hybrid-electric vehicles (HEVs) is placing new emphasis on the need for battery management to monitor voltage levels and provide car makers with the means to reduce battery weight, size and cost. Because HEV batteries operate at high voltages of up to 600 V, isolation is required for safe and reliable operation. Analog Devices is addressing these needs by expanding its portfolio of AEC-Q100 products with the...

Silicon Labs today introduced a family of digital isolators that offers the highest channel count, performance and data rate for demanding applications with isolation ratings up to 5 kV. The new Si86xx 3.75 kV and 5 kV digital isolators replace optocouplers in target applications requiring robust operation and high levels of insulation protection such as industrial automation and drives, motor control and medical systems. With its 5 kV rating, th...

Silicon Laboratories has announced the Si823x ISOdriver family, said to be the industry’s fastest and most integrated isolated gate drivers. Ideal for power supplies, motor control and lighting systems, the ISOdriver family integrates a two-channel isolator and dual driver into a single chip while improving power efficiency, enabling customers to increase power supply density and performance.

Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced that Elster, a global leader in smart metering solutions, has chosen the Si8422 5 kV digital isolator IC for its sophisticated AS1440 electronic polyphase meter designed for Smart Grid applications.

Avago Technologies announced two new miniature voltage/current threshold detection optocouplers for use in a wide range of industrial control applications. The ACPL-K370/K376 optocouplers are designed to detect AC/DC sources and convert the voltage to a logic interface across an optical coupling barrier to provide safe isolation in electronically noisy environments found in industrial applications. These voltage/current sensing optocouplers are i...

Avago Technologies today announced an extended temperature 2.5 Amp gate drive optocouplers for use in a wide range of industrial applications. Avago’s ACPL-312U, which is a member of the R2CouplerTM family, incorporates an alloy lead frame to offer superior heat dissipation, which allows it to operate over an extended industrial temperature range from -40 to 125 degrees C. These new extended temperature optocouplers from Avago target design...

Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced the 2.5 A peak-output drive ACPL-H342 and ACPL-K342 optically isolated IGBT gate drivers that feature a built-in Miller clamp, Rail-to-Rail output voltage, under-voltage lockout (UVLO) circuitry and protection against IGBT cross-conduction and current “shoot-through” for safe an...

Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a new optocoupler available in special packages designed for use in renewable energy applications, here at the Electronica 2010 trade fair. The new ACNV4506 optocoupler provides robust electrical signal isolation as an Intelligent Power Module (IPM) interface or Insulated Gate Bipolar Trans...
