Avnet Memec has signed a new pan-European distribution agreement with Intersil. The new agreement will take effect from today. It will make Avnet Memec a key distribution partner for Intersil?s...

The simple I2C bus connects controllers and peripheral devices. In automotive and especially hybrid electric vehicle applications, controllers or peripherals are isolated from the bus to avoid interference or harmful voltage levels. Usually, optocouplers are being used, but this increases the cost and complexity disproportionally. Digital isolators have the potential to simplify I2C design in electric and hybrid-electric vehicles. The cost-effective I2C bus uses bidirectional lines to transmit and receive signals over the same wire, allowing two-wire signalling of clock and data. Optocoupler-based isolation increases cost and complexity of the I2C interface because unidirectional optocouplers must be accommodated by separating...

One of the most annoying tasks for electronic design engineers is securing standard conformity. The sizes of descriptions for IEC, DIN and EN usually range between the telephone directory for Greater Londonand the Encyclopedia Britannica. However, most of the more boring steps can be automatized. A tool for the efficient application of standards and norms for safety-critical electronic systems is »RiskCAT«, distributed by Hitex. It has recently been adapted to edition 2 of the basic safety standard IEC 61508, which was published as final English version in April 2010. As an optional component, a module for comparing IEC 61508 Edition...
