ON Semiconductor and ConvenientPower Systems Announce Strategic Partnership for Automotive Wireless Charging Technology
Published2018.01.11 10:08ON Semiconductor has announced a strategic partnership with ConvenientPower Systems (CPS). Through this collaboration, CPS will design, develop, and sell automotive wireless charging solutions using ON Semiconductor's NCV6500 application-specific power management controller.
This integrated solution initiative is based on a single architecture that can scale multiple devices and coils up to 15W. The patented new technology for FOD (Foreign Object Detection) prevents overcurrent from foreign objects during charging, enabling safe operation with simple "place and charge" capability and providing users with a wide charging field.
ON Semiconductor's NCV6500 power management controller provides essential building blocks for inductive charging that comply with both Qi and PMA standards. Operating from a single 5V supply, the NCV6500 includes five differential and single operational amplifiers as well as two comparators featuring magnetic hysteresis and deglitch (fault control).
Based on a full NMOS H-bridge driver, the NCV6500 features on-chip clock generation including phase shift and duty cycle control. The device also integrates meaningful critical protection functions such as coil voltage sensing, bridge current sensing, overvoltage and overcurrent protection.
Majid Kafi, Senior Director and General Manager of System Power Solutions at ON Semiconductor, stated: "ON Semiconductor has invested significantly in wireless charging, particularly multi-protocol solutions related to the 15W sweet spot in this market. Through this partnership with CPS, we will integrate our key energy efficiency technologies and strengths implemented within the ASIC with CPS's system knowledge to deliver a total solution meeting demanding automotive requirements. Additionally, our solution will combine industry-leading FOD, certification and firmware support exceeding ASIC capabilities."
Camille Tang, President of CPS, said: "Integrating in-vehicle wireless power requires proven technological innovation and safety performance. We are very pleased to accelerate the integration and optimization of automotive wireless charging platform performance through ON Semiconductor, which has leadership in chip technology, manufacturing, and distribution."
Comprehensive evaluation boards, integrated coil modules (Qi) simulation, and samples for pilot evaluation are scheduled to be available from January 2018, which is expected to further simplify rapid development of wireless charging applications.
