Nexperia launches pioneering silicon-based OPEN-Alliance-compliant ESD protection for
automotive Ethernet Nexperia, the expert in discrete and MOSFET components and analog and logic ICs, today announced the launch of industry’s pioneering silicon-based, OPEN Alliance-compliant ESD protection for 100BASE-T1 and 1000BASE-T1 automotive Ethernet systems.
The OPEN (One-Pair Ether-Net) Alliance Special Interest Group (SIG) is a non-profit alliance of automotive industry and technology providers, who collaborate to encourage a wide scale adoption of Ethernet-based networks as the standard in automotive networking applications. Its work is meant to prepare IEEE and other international standards. Nexperia is a technical member of the OPEN Alliance SIG, and has developed fully
OMC’s new hermetically-sealed FDE851HLBF infra-red fibre optic emitter optimises long-term reliability in challenging environments
Specialist 850nm device delivers signal integrity with high intensity beam
OMC, the pioneer in optoelectronics design & manufacture, has released a hermetically-sealed 850nm fibre optic transmitter diode which delivers a high intensity output for coupling into multimode fibres even in challenging environments. Designed for applications where long term reliability is paramount, this device is highly specialised with very few similar products available on the market globally. It suits a wide range of fibre optic applications including datacomms, sensing, encoding, instrumentation and signalling, ensuring speed and integrity of signal over a long operating life.
The FDE851HLBF 850nm emitter features a hermetically-sealed TO-can body with glass optical window that helps protect the device internals from atmospheric conditions. The device features fast rise/fall times allowing high speed operation in the tens of MHz, and contains integral micro-optics which focus the beam to a very narrow point which delivers efficient coupling into multimode glass optical fibres as small as 50µm, achieving a typical launch power of 30µW at 100mA into 50/125 fibre.
Many fibre-optic emitters make use of a clear plastic cap which is pressed on to the device header. While this provides a degree of physical protection to the LED chip, wire-bond and internal optics, it is unusual for such a cap to provide a hermetic seal, meaning that the potential long-term effects of environmental characteristics such as humidity on the device internals must be carefully considered in applications where long service-life is important. By contrast, the hermetically sealed housing of the FDE851HLBF eliminates this variable, as air from the operational environment cannot reach the internal components.
omc-uk.com New Lattice mVision solutions stack accelerates
low power embedded vision development Lattice extends its leadership in delivering complete, easy-to-use solutions stacks
• Solutions stack includes customizable reference designs for popular embedded vision use cases such as image sensor bridging, aggregation, splitting, and processing
• Includes support for new Lattice Nexus™ platform and CrossLink-NX™ FPGAs

from Power Integrations expands to 400 W High-voltage half-bridge motor-driver is 99.2%-efficient; needs no heatsinks and reduces software certification time and expense
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced that its BridgeSwitch™ integrated half-bridge (IHB) motor- driver IC family has been expanded and now supports applications requiring up to 400 W. BridgeSwitch ICs feature high- and low-side advanced FREDFETs (Fast Recovery Diode Field Effect Transistors) with integrated lossless current sensing, resulting in inverter efficiency of up to 99.2% in brushless DC (BLDC) motor-drive applications. This industry-leading efficiency performance along with the distributed thermal footprint provided by the IHB driver eliminates the need for a heatsink, reducing both system cost and weight.
The new 400 W BRD1167 and BRD1267 BridgeSwitch ICs deliver up to 1.33 A RMS, 11.5 A DC output peak current. Like the rest of the BridgeSwitch family, they are self-powered and available in the same compact InSOP-24C surface-mount package. These devices can drive single- or multi-phase high-voltage, synchronous or asynchronous motors, and support all popular MCU and motor control algorithms. All BridgeSwitch ICs feature cycle-by-cycle hardware–based overcurrent, over/under-voltage and over- temperature protection features, which eliminate the software component from many protection functions. This simplifies IEC 60335 and 60730 certification, saving time and cost.
Like other BridgeSwitch family ICs, the new, uprated BRD1167 and BRD1267 devices also feature built-in device protection and system monitoring and a robust single-wire preventive maintenance interface which enables communication between the motor microcontroller and up to three BridgeSwitch devices. Each BridgeSwitch device may be configured with different high- and low-side current limits, eliminating role of the microcontroller and external circuitry in protecting the system from open or shorted motor windings.
Technical support for the BridgeSwitch BLDC motor-drive family of ICs is available from the Power Integrations website at:

Rugged, miniature EMM connector available as ‘MICRO HDAS‘
providing second source security of supply for hi-rel customers Nicomatic, the French company recognized for the design and manufacture of miniature, rugged connector systems, and Amphenol Socapex, the world-renowned manufacturer of rugged interconnection solutions have signed a dual-sourcing agreement, whereby Amphenol Socapex will sell Nicomatic’s modular, 1.27mm pitch rectangular EMM connector family under the brand MICRO HDAS. This will benefit customers in hi-rel industries who require a dual source for this innovative connector.
Under the global agreement, a selection of Nicomatic’s EMM series connectors will be
integrated into the Amphenol Socapex portfolio. Both companies will use their respective channels and customers to address new markets with the high performance connector, and each company will deploy its own strategy and use its own networks to respond to satisfy the demands of its customers, regardless of the geographic area targeted.
Comments Olivier Nicollin, CEO of Nicomatic: “We approached this partnership in the spirit of co- operation. We are looking to accelerate the adoption of a connector that we are proud of, but above all, we are convinced that this agreement offers added value to our customers. Our partners have trusted us for a long time because our connectivity meets their requirements.
We are committed on a daily basis to developing an ecosystem in which our customers are central, thanks to the strong links we create and develop with our employees and also with our suppliers, or in this case, even with our ‘competitors’. This philosophy guides the commitments we make, and this initiative with Amphenol Socapex is a perfect example of where we choose to work together to better serve our customers.”
