摘要： A driver unit for programming an output current of a driver with an output stage for providing the output current and a primary control stage with a control input for controlling the output current has been provided. The driver unit includes a programmable memory unit for storing data corresponding a target value of the output current, a programming signal circuit configured to provide electric signals for writing the data in the programmable memory unit as well as a controller circuit with a controller. The controller is operatively connected to the programmable memory unit and is configured to read out the data stored in the programmable memory unit and generate a controller output signal for adjusting the output current of the driver, based on the data stored in the programmable memory unit.
