Description

The STWBC86 is a highly integrated monolithic wireless power transmitter solution

suitable for applications up to 5W.

This solution requires low external BOM count. Because of the integrated low

impedance Full/Half bridge inverter, STWBC86 achieves high efficiency and low

power dissipation.

I2C interface allows firmware and platform parameters to be customized and the

device can be configured using the embedded FTP.

Additional firmware patching also improves application flexibility of STWBC86.

The Flip Chip package and low BOM count make the device suitable for very

compact applications.
