STWBC86JR Inductive Wireless Charger Power Transmitter
STMicroelectronics' highly integrated monolithic wireless power transmitter requires a low BOM count
STMicroelectronics' STWBC86JR is a highly integrated monolithic wireless power transmitter solution suitable for applications up to 5 W. This solution requires a low external BOM count. Because of the integrated low-impedance full/half-bridge inverter, STWBC86JR achieves high efficiency and low power dissipation.
An 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 the application flexibility of STWBC86JR. The flip chip package and low BOM count make the device suitable for very compact applications.
