  • Arrangement and method for adjustment of the slope times for one or more drivers and a driver circuit
    Patent number: 6777974
    Abstract: The invention relates to an arrangement (10) and a method for adjusting the slope times of one or more drivers (90) in such a way that the adjustment is essentially independent of external conditions. The invention also relates to a driver circuit. The arrangement (10) is provided with a device (20) for detecting the time history of an output voltage that is output and supplied to a load (12) by means of the driver/s (90). The measured time values are converted into an output voltage value in a device (36) for converting the measured time history of the output voltage. Moreover, a device (40) for generating a reference voltage value is provided. The device (40) is connected to a device (60) for predetermining a desired slope time for the driver/s (90), whereby the slope time is essentially independent of external conditions.
