摘要： An implantable medical device includes a low-power circuit, a high-power circuit, and a dual-cell power source. The power source is coupled to a dual-transformer such that each cell is connected to only one of the transformers. Each transformer includes multiple windings and each of the windings is coupled to a capacitor, and the capacitors are all connected in a series configuration. The low power circuit is coupled to the power source and issues a control signal to control the delivery of charge from the power source to the plurality of capacitors through the first and second transformers.

摘要： An implantable medical device includes a low-power circuit and a multi-cell power source. The cells of the power source are coupled in a parallel configuration. The implantable medical device includes both a low power circuit that is selectively coupled between the first and second cells and a high power output circuit that is directly coupled to the first and second cells in a parallel configuration. An isolation circuit is coupled to the first cell, the second cell and the low power circuit to maintain a current isolation between the first cell and the second cell at least during delivery currents having a large magnitude that are delivered to the high power output circuit.

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.
