ABSTRACT:
An implantable medical device (IMD) includes one or more semiconductor switches and one or more switch driver circuits. The semiconductor switches, in response to one or more switch-on and switch-off commands that each have a voltage magnitude, switch between a conductive state and a non-conductive state, respectively, to thereby selectively supply one or more therapy pulses using electrical energy from an electrical energy source. The switch driver circuits, in response to drive commands, selectively supply the switch-on and switch-off commands to the semiconductor switches. The switch driver circuits, using a portion of the supplied therapy pulses, increase the voltage magnitudes of the switch-on and switch-off commands to a magnitude that maintains the switch in the conductive state or the non-conductive state, respectively, while the therapy pulses are being supplied.
