Abstract
An implanted device such as a cochlear implant system includes a housing containing stimulating pulse generating circuitry, and a plurality of electrodes external of the housing and receiving the pulses. Between the pulses, parasitic voltages may build up between the electrodes. In order to control the inrush current due to these parasitic voltages, multi-position switches are provided which selectively couple the electrodes to resistors selected to dissipate the voltages at a preselected maximum current to protect the body organs.
