BQTESLA150LP Applications

The bq51013EVM-725 evaluation module (EVM) demonstrates the receiver portion of the bqTESLA™wireless power system. This receiver EVM is a complete receiver-side solution that produces 5 V out at upto 1 A when coupled with the bqTESLA™ transmitter. The bq51013EVM-725 device shown on this EVMalong with external components that support the device for a complete solution. • The bqTESLA™ receiver can be used in any number of low-power battery portable devices as a powersource for charging. With contact-free charging capability, no connections to the device are needed. • Output voltage of 5 V up to 1 A • External adapter switchover and control circuit • • Frame is configured to provide correct receiver to transmitter spacing. • Room above coil for testing with battery, key for tuningLow-profile, external pick-up coil
