Dual TrenchFET MOSFETs suit vehicle telematics
Believed to be one of the industry's first automotive-qualified dual MOSFETs in an asymmetric package, the SQJ940EP and SQJ942EP dual n-channel TrenchFET power MOSFETs have been announced by Vishay. Operating over a wide temperature range from -55 to +175°C, the MOSFETs provide the ruggedness and reliability required for in-vehicle applications.
DC/DC converter balances high voltage battery stacks
Featuring isolated balancing design and system telemetry, Linear’s LT8584 monolithic flyback DC/DC converter is designed to actively balance high voltage stacks of batteries. The active balancing offered with the DC/DC converters redistributes the charge from the stronger cells to charge the weaker cells during discharge. This enables the weaker cells to continue to supply the load, extracting 96% of the entire stack capacity where passive ...
Qi-certified wireless power receiver IC for smartphones
Toshiba Electronics Europe have announced the introduction of a new wireless power receiver IC, the TC7761WBG. Compliant with Qi Standard Low Power Specifications version1.1, the TC7761WBG wireless IC will be used in wireless power supply applications, such as smartphones and mobile accessories.
Powervation's PV3012 used in Murata's new DC/DC module
The PV3012 digital controller from Powervation is being used in a new DC/DC module from Murata. Designated the OKLF-T/25-W12N-C, the new module is a non-isolated, DC/DC converter delivering a maximum of 25 A at an output of 1.2 V, when operating up to 70°C with a 200 LFM airflow. Ideal for powering the latest FPGAs and ASICs in netwoking and computing, the adjustable outputs of the OKLF-T/25-W12N-C provide precision regulation from 0.69 V t...
Digital POL regulator for ICT and industrial applications
Ericsson has today introduced a third-generation digital point-of-load regulator with Dynamic Loop Compensation. The new Ericsson 3E series BMR463-25A offers a 25% increase in output current over the previous generation BMR463-20A, but is supplied in a fully compatible footprint. It also includes a full set of PMBus commands for fully monitoring and dynamically controlling the energy delivered to strategic components to a very low and highly econ...
Save fuel by stopping the engine before the vehicle
Helping to combat the ever rising cost of fuel, Bosch has developed a new start-stop coasting function which stops the engine when the vehicle is in motion to save fuel. The new system stops the engine whenever the vehicle can maintain its speed simply by rolling (i.e. on a slope). As soon as the driver touches the accelerator or brake pedal, the engine starts up again. Bosch's new start-stop coasting function enables travel in zero-emission, noi...
Packaging power for the next generation
The concept of hybrid and electric vehicles is far from new, but the challenges in the ascendance of the latest generation require new solutions. By Benjamin Jackson Senior Manager, Automotive Power Switch & Power Module, Product Management & Business Development, with International Rectifier.
Transformer series extends slection for SN6501 power driver
Wurth Electronics Midcom and Texas Instruments have jointly developed a series of four new transformers which extends the transformer selection for the SN6501 power driver. The new series of parts is an extension to the 2500VAC isolated parts released last year by Wurth. The new series is a 5000VAC isolated series designed to comply with the requirements for the medical electrical equipment standard, IEC60601-1, for providing tw...
Driving down power
While the increased use of electronic systems in vehicles is delivering improved safety and comfort for the driver and passengers, their power demands must not be overlooked. Andy Birnie, Automotive MCU Systems Engineering Manager with Freescale Semiconductor, takes a closer look in this article from ES Design magazine.
Bond wireless building blocks provide a new approach to power modules
The Hybrid Electric Vehicle is bringing new challenges and opportunities for power semiconductor packaging, in particular those without bond wires. Here we discuss how using discrete bond wireless building blocks in the CooliR2DIE approach can be used to develop a complete module. By Ben Jackson, Senior Manager, Automotive Power Switch & Power Module Product Management & Business Development, for International Rectifier.
