3 / 96 page  1 Block diagrams 1.1 STWBC2-HP architecture The following image illustrates the overall system blocks implemented in the STWBC2-HP architecture. The STWBC2-HP is a system-in-package combining an STM32G071 MCU die with a Wireless Power specific die which integrates several application-specific functions. The STWBC2-HP supports both half-bridge and full-bridge coil driver topologies, together with a digital DC-DC controller, which regulates the input voltage of the bridge in order to control the amount of power transmitted to the receiver. The digital controller also regulates the inverter operating frequency and duty cycle to further adjust the amount of power increasing the overall efficiency at light load. It implements the WPC Qi protocol, including Foreign Object Detection (FOD) extensions. An accurate Q-factor measurement provides enhanced FOD. The STWBC2-HP is able to manage both WPC Baseline Power Profile (up to 5 W) and Extended Power Profile (EPP). Figure 1.
