High Energy Savings for Less Money

Posted on 17 July 2012

      Low-cost 8-bit MCUs support easy convergence to energy efficient designs Using sophisticated power concepts based on optimized microcontrollers provide enormous energy saving potentials in various applications. Both improved energy efficiency and reduced system costs are the driving factors in modern motor control designs used in fans, pumps, compressors, geared motors and for [...]

Improved Measurement and Analysis Yields Cost-Effective Standby Battery Monitoring

Posted on 17 July 2012

      Monitoring of standby battery parameters must be comprehensive The infrastructure that underpins contemporary society must operate with very high reliability. In contrast to the advanced technology deployed in data storage centres, internet server farms and communications central offices, most of them rely for near-100% “uptime”, or system-availability, on a very mature technology; [...]

Power Management IC Simplifies Design for Bluetooth Headsets

Posted on 17 July 2012

      The perfect solution for space limited applications This article details recent developments in power supply circuits enabling simplified designs compared to discrete solutions. The PMU discussed also reduces the board space needed significantly for Bluetooth headsets. By Thomas Schaeffner, Texas Instruments, Freising   Recently Bluetooth headsets have become popular not only as [...]

Acoustic Flatness Measurement Enhances Die Attach Analysis of Power Device

Posted on 17 July 2012

      An ultrasonic transducer raster-scans the flat surface Thermal management is always a concern when using power devices. Acoustic micro imaging looks nondestructively at the internal features of power devices; specifically, this method images the interfaces between materials. The quality of the bond at an interface, and the presence or absence of delaminations [...]

Effective Battery Charging and Management

Posted on 17 July 2012

      This can save the environment while improving customer experience The awareness of environmental impact has extended to the segment of portable electronics. Consumers increasingly demand better performance and “sexy” industrial designs. At the same time, they expect products to minimize any negative impact on the environment. By George Paparrizos, Director, Product Marketing, [...]

Application Guides the MOSFET Selection Process

Posted on 17 July 2012

      Packaging can certainly impact conduction loss Given the maturity of MOSFETs, selecting one for your next design may seem deceptively simple. Engineers are familiar with the figures of merit on a MOSFET data sheet. Selecting a MOSFET requires the engineer to use their expertise in scrutinizing different specifications for individual applications. By [...]

Low-Cost Highly Integrated Gate Driver Core

Posted on 10 July 2012

    SCALE-2 Simplifies Custom-Specific Solutions The highly integrated SCALE-2 chipset allows the time-to-market, development effort and production cost of custom-specific IGBT gate drivers to be dramatically reduced. As an example, the new 2SD300C17 is presented that is compatible with the 2ED300C17 from Infineon in mechanical, functional and parametric terms. The chipset has been developed [...]
