bq501210 bqTESLA™ Wireless Power TX EVM
The bq501210EVM-756 wireless power transmitter evaluation module from TI is a high-performance,
easy-to-use development module for the design of wireless power solutions. The bq501210 evaluation
module (EVM) provides all the basic functions of a Qi-compliant, wireless charger pad. The 15-V to 19-V
input, single coil transmitter (TX) enables designers to speed the development of their end-applications.
The EVM supports WPC v1.0, WPC v1.1, and WPC v1.2 receivers (RX) and supports output power up to
15 W when paired with a WPC v1.2 15-W receiver.
