ON Semiconductor & CPS Collaborates for Automotive Wireless Charging

ON Semiconductor has announced a strategic collaboration with Convenient Power Systems (CPS) whereby CPS will design, develop and market in-vehicle wireless charging solutions using ON Semiconductor’s NCV6500 application dedicated, power management controller.

The combined initiative is based around a single architecture that is scalable for multiple devices and coils to 15 W. A novel and patented technique for Foreign Object Detection (FOD) ensures safe operation, while the broad charging field provides a true “drop-and-charge" experience for users.

ON Semiconductor’s NCV6500 power management controller provides the essential building block for inductive charging that is compliant with both Qi and PMA standards. Operating from a single 5 V supply, the NCV6500 includes five differential and single-ended operational amplifiers, as well as two comparators with hysteresis and deglitch.

Based upon full NMOS H-bridge drivers, the NCV6500 has on-chip clock generation, including phase shifting and duty cycle control. The device also incorporates significant and important protection features such as coil voltage sense, bridge current sense, and over voltage and over current protection.

Combined coil module (Qi) simulation and preliminary sampling, as well as a comprehensive evaluation board, are expected to be available from January 2018 to further simplify the rapid development of wireless charging applications.

A demonstration of the NCV6500 wireless charging technology will be available at ON Semiconductor’s demo room at the 2018 Consumer Electronics Show, January 9–12 in Las Vegas, NV. To learn more, click here.
