Electronic circuit configuration and corresponding method for controlling actuators such as valves or injectors
First Claim
1. An electronic circuit arrangement for controlling at least one actuator comprising at least one driver circuit with a control input and a resetting input for electrically controlling the actuator as a function of the data which is incoming at the control input, a control unit which is connected at the output end to the resetting input via a resetting line and to the control input of the driver circuit via a control line, and comprising a signal input which is connected internally to the control unit for the external connection of a switching element, the control unit placing the driver circuit in a predefined state when the switching element is activated via the resetting line, wherein the signal input for the switching element is coupled with the resetting input of the driver circuit via a signal path while bypassing the control unit.

Abstract
Electronic circuit arrangement for controlling at least one actuator, in particular for controlling the valves and/or the injectors of an injection system of an internal combustion engine, having at least one driver circuit (1, 2) with a control input (control line 1, control line 2) and a resetting input (RESET) for electrically controlling the actuator as a function of the data which is incoming at the control input (control line 1, control line 2), a control unit (3, 4) which is connected at the output end to the resetting input (RESET) via a resetting line and to the control input (control line 1, control line 2) of the driver circuit (1, 2) via a control line, and having a signal input (Kl15) which is connected internally to the control unit (3, 4) for the external connection of a switching element, the control unit (3, 4) placing the driver circuit (1, 2) in a predefined state when the switching element is activated via the resetting line, the signal input for the switching element being connected to the resetting input (RESET) of the driver circuit (1, 2) via a signal path (9) while passing the control unit (3, 4).
