ST8024L Smart card interface

Description
The ST8024L is a complete low-cost analog interface for asynchronous Class A, B and C smartcards. It can be placed between the card and the microcontroller with few external components to perform all supply protection and control functions. ST8024LCDR and ST8024LCTR are compatible with ST8024 (with the exception of Vth(ext)rise/fall).

STEVAL-IHM025V1 1 kW 3-phase motor control demonstration board featuring the IGBT SLLIMM™ STGIPL14K60

Description
The STEVAL-IHM025V1 is demonstration board is an AC/DC inverter that generates a three-phase waveform for driving three- or two-phase motors such as induction motors or PMSM motors up to 1000 W with or without sensors.
The system represents a universal, fully-evaluated and populated design consisting of a 3-phase inverter bridge based on the 600 V IGBT SLIMM™ (small low-loss intelligent molded module) in the SDIP 38L package mounted on a heatsink. The STGIPL14K60 integrates: high voltage, short-circuit rugged IGBT and high voltage gate drivers with advanced features like integrated op-amp suitable for advanced current sensing. Thanks to this integrated module, the system has been specifically designed to achieve power inversion in a reliable and compact design. The system architecture of the module is based on integrated advanced features and is specifically designed to achieve fast and accurate conditioning of the current feedback, thereby matching the typical requirements in field-oriented control (FOC).
The board is designed to be compatible with single-phase mains, supplying from 90 VAC to 285 VAC or from 125 VDC up to 400 VDC for DC voltage.

L6566BH Multi-mode controller for SMPS

 Description
The L6566BH is an extremely versatile current-mode primary controller ICs, specifically designed for high-performance offline flyback converters running off rectified 3-phase input line. It is also suited for single-stage single-switch input-current-shaping converters (singlestage PFC) for applications supposed to comply with EN61000-3-2 or JEITA-MITI regulations.

Geo-Magnetic Modules from STMicroelectronics Extend Battery Life and Boost Accuracy in Mobile Compassing Applications

Current consumption down by 50%, magnetic sensing resolution up by 30% in ST’s newest digital-compass device

Geneva, April 19, 2011 - STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications and the leading supplier of MEMS (Micro-Electro-Mechanical Systems) for consumer and portable applications, has introduced a new generation of geo-magnetic modules. The ultra-low-power device addresses advanced navigation and location-based services in portable consumer applications by integrating high-resolution three-axis sensing of linear and magnetic motion in a 5 x 5 x 1mm package. iSuppli, a leading market research firm, forecasts rapidly rising global demand for digital compasses; it expects the market to grow at a CAGR of 12%, from $1.1 billion in 2010 up to $1.9 billion in 2015.

The integration of high-performance motion and magnetic sensing enables enhanced electronic compassing in mobile phones and other personal electronic devices, including direction finding, map/display orientation, location-based services and pedestrian dead reckoning. This latest addition to ST’s MEMS portfolio, the LSM303DLM geo-magnetic module has been designed and produced using the same micromachining technology process that ST has already successfully applied to more than one billion motion sensors sold in the market.
