Abstract
Gate protection clamping circuits and techniques with controlled output discharge current are provided. Circuits and methods according to the invention are implemented to relatively rapidly disengage single or multiple loads from a power supply without creating thermal overload. This is accomplished by first rapidly shutting OFF the power device coupling the power source to the load, and then further discharging the output capacitance with a substantially smaller, preferably regulated, current. Additional external devices may be added if faster discharge of the output capacitance is desired.
