Abstract
A wireless charging and data transmission system that includes first and second half-bridges coupled in parallel between supply and ground nodes. Each half-bridge includes high-side and low-side transistors. A first high-side driving circuit drives the control terminal of the high-side transistor of the first half-bridge with a first bootstrap voltage at a first node, and a second high-side driving circuit drives the control terminal of the high-side transistor of the second half-bridge with a second bootstrap voltage at a second node. A charge pump circuit generates and maintains a master bootstrap voltage at a master node, which is equal to the voltage at the supply node plus a given voltage. A switch circuit couples the master node to the first node during the low-side conduction period of the first half-bridge and couples the master node to the second node during the low-side conduction period of the second half-bridge.
