Beijing February 5, 2010 / PRNewswire Asia - electric and hybrid electric vehicle (HEV) the continued popularity of the application makes the battery management has become increasingly important not only to monitor the battery voltage, but also for car manufacturers to reduce the battery weight, small size and lower costs. Because HEV battery voltage to 600 V, to ensure safe and reliable, the need for appropriate quarantine measures. Analog Devices Inc. a leading global supplier of high performance signal processing solutions, has introduced a new integrated supply isolated power with 4-channel isolator numerical expansion of the AEC-Q100 portfolio of products to meet those needs. ADuM540xW series of products adopt the latest ADI iCoupler (R) chip micro-level proprietary design technology of the processor. So far, this technology has been applied to over 300 million of separate channels, extensive coverage, including automotive supply, industrial, medical, power and consumption systems, including a variety of applications. The New Digital Isolators with isopower ADI (R) proprietary integrated isolated DC / DC converter technology can deliver up to 500mW output 5V single power supply stability.
In HEV applications, this isolation allows the integrated power supply across the isolation barrier for the monitor battery, without battery consumers. With the discrete solutions (such as opto-coupler with an external DC / DC converter), vgp-bpl2 ,sony vgp-bps2 ,Comparative ADuM540xW device is a better choice because they use an area of 10mm x 10mm mounting small package, the discrete solutions to reduce the number of components to the individual components can be reduced to 70% of the surface of the circuit board and up to 50% of the cost.
“With the hybrid / electric battery technology develops vehicles require isolation, technology type energy supply to greater integration and resistance to temperature, and the need for packaging signals from external digital interface. “Signal Processing ADI for Automotive Applications Business Unit Director Bill Riedel said:” ADI iCoupler digital isolators with power supply isolated, not only small but also with solutions optocoupler, power consumption can be reduced by 50%, thus contributing to car manufacturers to produce greener cars now. ”
ADuM540xW produced specifically for the HEV motor drives and system design of battery management, the AEC-Q100 specified automotive certification -40 ℃ to +105 ℃ temperature limit of quality standards. The AEC-Q100 isopower new insulators may be configured in a variety of channels to provide multiple channels of isolation, satellite m50 battery, satellite m55 battery , support data rates up to 25Mbps. Based on CMOS technology at both ends of the series ADuM540xW devices are operating voltage 4.5V to 5.5V.
