1. An implantable medical device, comprising:

  • a first cell;

    a second cell;

    a low power circuit selectively coupled between the first and second cells, wherein the low power circuit receives a first level of current from the first and second cells;

    an isolation circuit coupled to the first cell, the second cell and the low power circuit; and

    a high power output circuit directly coupled to the first and second cells in a parallel configuration for delivery of an electrical stimulation therapy, wherein the high power output circuit includes a first cell switch configured to couple the first cell to the high power output circuit for delivery of charge and a second cell switch configured to couple the second cell to the high power output circuit for delivery of charge,wherein the isolation circuit is configured to maintain a current isolation between the first cell and the second cell such that a second level of current is delivered from both the first and second cells to the high power output circuit, andwherein the second level of current is greater than the first level of current.
