Note : Your request will be directed to STMicroelectronics.

The STWBC-WA from STMicroelectronics is a digital controller for wireless battery charger transmitters used for wearables and smart watch applications. This power transmitter is responsible for controlling the transmitting coil and generating the correct amount of power requested by the receiver unit. The receiver unit continuously provides the transmitter the correct power level requested, by modulating the transmitter carrier through controlled resistive or capacitive insertion. Generating the correct amount of power guarantees the highest level of end-to-end efficiency due to reduced energy waste. It also helps to maintain a lower operational temperature. It supports under 3 W wireless charging applications and requires a supply voltage of 3 to 5.5 V. It is available in a surface mount package and is ideal for IoT, remote controllers, smart watches and helathcare applications.
