Abstract
The turn-off delay time of a low-side driver (output power transistor), may be independently reduced and eventually made identical to the turn-on delay time by employing an auxiliary current generator that may be controlled by the same switching signal that controls a current generator employed for discharging the control node of the low-side driver, in order to provide an augmented discharging current during a first phase (only) of a turn-off process. The contribution to the capacitance discharge current provided by said third current generator is automatically interrupted by means responsive to the voltage present on the driving node of the low-side driver, when it approaches saturation.
