Product Details

The STWBC-EP is the digital controller for the wireless battery charger (WBC) transmitters (TX) from STMicroelectronics optimized for Extended Power Profile (EPP) Wireless Power Consortium (WPC) 1.2 certified applications up to 15 W. It offers the most flexible and efficient solution for controlling the power transfer to a receiver (RX) in WBC-enabled applications such as smartphones, tablets and other battery-powered devices that use the electromagnetic induction for recharging. The TX is responsible for controlling the transmitting coil and generating the correct amount of power requested by the RX.
