An integrated circuit having a unit for controlling a load of an inductive nature, which unit includes a first output transistor having a first control electrode and a first main current path, a second output transistor having a second control electrode and a second main current path, a control stage coupled to the control electrodes and adapted to control the output transistors. An output terminal is coupled between the main current paths and adapted to connect the load. In order to limit a voltage transient appearing on the output terminal, as a result of an interruption of a current flowing through the load, the control stage is coupled to the output terminal and is adapted to detect a first voltage transient on the output terminal, to turn on the second transistor in response to the first voltage transient, to detect a second voltage transient on the output terminal, which second voltage transient is opposed to the first voltage transient, and to turn off the second transistor in response to the second voltage transient. |
