Abstract
An implantable medical device (IMD) includes multiple stimulation engines (SEs) for independently stimulating respective electrode sets of a lead system. A voltage multiplier (VM) is configured to generate an adjustable target voltage at an output node. Each stimulation engine includes first switching circuitry to switchably connect an anodic node of the SE to the VM output node and second switching circuitry to switchably connect a cathodic node of the SE to a current sink circuit. Discharge switching circuitry may be disposed between the anodic and cathodic nodes of each SE. A selector and associated digital control logic block are operative to generate control signals for independently controlling respective SEs such that each SE may be activated to stimulate or discharge a corresponding select set of electrodes independently from or in concert with remaining SEs.
