摘要:
An implantable medical device includes a low-power circuit, a high-power circuit, and a multi-cell power source. The implantable medical device delivers stimulation therapy to cardiac tissue. The cardioversion energy is delivered across through electrodes that are coupled to terminals of the high-power circuit. A protection circuit for protecting the low-voltage circuit components from high voltage pulses includes a first segment coupled to a first of the electrodes and a second segment coupled to a second of the electrodes, the components of the low-voltage circuit being coupled to the transthoracic protection circuit portion, and a reference potential corresponding to a ground potential, wherein the first and second segments of the transthoracic protection circuit portion are coupled to the reference potential in a parallel configuration.
