A circuit for conveying information from a sender component to a receiver component is provided. The sender component is a high side component and the receiver component is a low side component or the sender component is a low side component and the receiver component is a high side component. The low side component is arranged to drive a first electronic switch of a half bridge and the high side component is arranged to drive a second electronic switch of the half bridge. The circuit includes a first voltage-decoupling device and a second voltage-decoupling device that are arranged such that a voltage conveyed from the sender component to the receiver component is modulated by the sender component and conveyed across the first voltage-decoupling device and the second voltage-decoupling device depending on the information.
