Abstract
To shorten the recovery time of a line driver (1) after an overvoltage on its output terminal (3), a current generating device (5) senses a voltage difference between the output voltage of the line driver (1) and its supply voltage (UB) plus a threshold voltage (UT'), and supplies a current (I) that is proportional to the sensed voltage difference up to a maximum current to the output (3) of the line driver (1) to raise its potential to thereby shorten its recovery time.
