Highly Integrated R 2Couplers Provide Safe Isolation With Improved Power Efficiency and Reduced Power Loss for Electric and Hybrid/Electric Auto Applications
SAN JOSE, Calif., Oct. 23, 2012 (GLOBE NEWSWIRE) -- Avago Technologies (Nasdaq:AVGO), a leading supplier of analog interface components for wireless, wireline, and industrial applications, today announced the addition of three new isolation optocouplers to their R 2Coupler family. These new automotive optocouplers provide safe isolation for electric vehicle (EV) and hybrid/electric vehicle (HEV) applications such as onboard charging systems and powertrain inverters in these vehicles while extending the working voltage range of existing R 2Couplers optocouplers.
These new devices provide high integration of functions in modules, isolated smart gate drives, analog sensing and digital communications. Powertrain inverters, onboard chargers and DC-DC converters draw on gate drives for driving power devices like MOSFETs and IGBTs. They need isolation amplifiers to sense high voltage bus levels and digital isolation to communicate status and feedback information from the high voltage side of the optocoupler to the microprocessor on the low voltage side."With industry trends targeting higher continuous isolation working voltage levels and higher levels of integration, our new optocouplers show our knowledge and commitment to these trends," said Cheng-Dee Lee, Business and Applications Development Director for Isolation Products at Avago. "By expanding our portfolio with enhanced feature sets and addressing isolation needs across markets, OEMs can easily balance their flexible design requirements. This allows them to meet the continual component challenge of integration that in turn reduces module size and volume of their end products."
