Abstract:
1. An apparatus, comprising: at least one pair of first and second transistors configured to form a current path to discharge current from an electromagnetic load, said first transistor comprising an inherent diode between channel couplings of the transistor; and a load controller configured to control switching on and off of said at least one pair of first and second transistors, and in a discharging mode of operation, to couple a control coupling of the second transistor to a first channel coupling of the second transistor, with said first and second transistors switched off, so that current from said electromagnetic load, crossing said inherent diode, creates a voltage between conduction couplings of said second transistor, wherein said load controller comprises a switch controlled to couple the control coupling of the second transistor to the first channel coupling of the second transistor when in the discharge mode of operation.
