Abstract:
1. An implantable medical device (IMD), comprising: one or more semiconductor switches adapted to receive electrical energy from an electrical energy source, each semiconductor switch coupled to receive one or more switch-on and switch-off commands, the switch-on and switch-off commands each having a voltage magnitude, each semiconductor switch operable, upon receipt of the switch-on and switch-off commands, to switch between a conductive state and a non-conductive state, respectively, to thereby selectively supply one or more therapy pulses using the electrical energy from the electrical energy source; and one or more switch driver circuits, each switch driver circuit adapted to receive drive commands and operable, in response thereto, to selectively supply the switch-on and switch-off commands to at least one of the semiconductor switches, each switch driver circuit coupled to receive a portion of the supplied therapy pulses and configured to 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.
