Small isolated gate drivers enable next-gen power switches
Analog Devices has announced small form factor isolated gate drivers designed for the higher switching speeds and system size constraints required by power switch technologies such as SiC and GaN, while still providing reliable control over switching characteristics for IGBT and MOSFET configurations.
ADI & Microsemi launch scalable SiC driver reference design
Microsemi and Analog Devices have announced a scalable SiC driver reference design solution at PCIM Europe 2017. The solution is based on a range of Microsemi SiC MOSFET products and ADI’s ADuM4135 5KV isolated gate driver. Both companies are exhibiting in PCIM's Hall 6; Analog Devices are on stand458, andMicrosemi on stand 318.
The IIoT reinvents the PLC
The programmable logic controller (PLC) that is today a mainstay of industrial automation is set for major changes in combination with the move to industrial internet of things (IIoT).

11mm SSO-8 gate drive optocouplers improve industrial drives
Broadcom Limited announced a new family of 5A and 3A gate drive optocoupler devices, the Avago ACNU-3430 and ACNU-3410, respectively. The devices are the first 5A and 3A gate drive optocouplers offered in the 11mm SSO-8 package for high voltage, space constrained industrial applications including 600VAC motor drives and 1kVDC solar inverters.
Optocouplers support satellites, spacecraft, and planetary rovers
A global provider of engineered electronics for performance critical applications,TT Electronics has announced the market introduction of its HCC100x series of radiation tolerant optocouplers. The devices are ideal for the isolation of electrical circuits within high-radiation deep spaceflight applications, including satellites, launch vehicles, space craft, and planetary rovers.
Industry’s first high-speed multi-channel PLC input isolators
Silicon Labs has introduced what it claims to be the industry’s first high-speed, multi-channel digital isolators designed to meet the demands of Programmable Logic Controller (PLC) applications. The Si838x PLC field input isolator family offers high-speed channels (up to 2Mb/s), exceptional channel integration (up to eight channels per device), bipolar input flexibility, high noise immunity and 2.5kVRMS safety isolation.
Bi-directional digital isolators improve flexibility
Designers can save space and achieve more flexible designs with the latest two-channel, bi-directional digital isolators from Maxim Integrated Products. The MAX14933 and MAX14937 transfer digital signals between circuits in both directions and provide complete galvanic isolation between two power domains, all while using fewer components to save board space.
5A gate drive optocouplers features unmatched noise immunity
Broadcom Limited has announced a new generation of 5A gate drive optocoupler devices, the ACPL-352J and ACNW3430, designed for a wide range of industrial applications including motor drives and power inverters. The devices feature superb common mode transient immunity (CMTI) of up to 100kV/μs, preventing erroneous gate driver failures in noisy environments. Both the ACPL-352J and ACNW3430 support up to 5A rail-torail output current, which elim...
DC/DC converters features operational life of 30 years
The BHT-319R-F4 series of DC/DC converters is designed for an operational life of 30 years at high temperatures in railway and industrial environments. The convection cooled units deliver 300W continuous output power over a -40 to +85°C temperature range without derating. By eliminating optocouplers and electrolytic capacitors, the MTBF of the units is significantly higher than in conventional converter designs.
