BQ500212AEVM-550(#1): 5W, 5V Inductive

Summary

The bqTESLA™ wireless power transmitter evaluation module from Texas Instruments is a high-performance, easy-to-use development module for the design of wireless power solutions. The single channel transmitter enables designers to speed the development of their end-applications.

The bq500212A EVM evaluation module (EVM) provides all the basic functions of a Qi-compliant, wireless charger pad. The EVM is intended to be used with bq51013BEVM-764 or any other Qi-compliant receiver.

The EVM supports both the WPC 1.0 and WPC 1.1 receivers. The transmitter EVM is a 5-V input design which powers a standard WPC low-power 5-W receiver.

The bq500212AEVM-550 evaluation module demonstrates the transmitter portion of the bqTESLA™ wireless power system. This transmitter EVM is a complete transmitter-side solution that powers a bqTESLA™ receiver.

The EVM requires a single 5-V power supply capable of up to 2 A to operate and combines the transmitter electronics, input power socket, LED indicators, and the transmitting coil on the single printed-circuit board (PCB). The open design allows easy access to key points of the electrical schematic.
