1. An apparatus for controlling the stimulation of neural tissue comprising: An implantable neural stimulator; an input device including a neural stimulation controller connected via a wireless link to the neural stimulator providing input for neural stimulation; at least one implantable electrode electrically connected to and driven by the neural stimulator and configured to stimulate neural tissue; an active current monitor taking a discrete integral in the time representation of an arbitrary waveform stimulation pulse within a set of provided arbitrary waveform stimulation pulses of the input for neural stimulation to calculate a charge per phase for the at least one electrode; a calculating device comparing the charge per phase of each stimulation pulse for the at least one electrode to a predetermined maximum charge per phase, and determining a reduced stimulation level for the at least one electrode by the amount necessary, not to exceed said predetermined maximum charge per phase for the at least one electrode; and a current pulse generator for stimulating said neural tissue according to said reduced stimulation level.
