Claim:
1. A neurostimulation device capable of being placed between a stimulation state and an electromagnetic interference (EMI) protection state, comprising: a plurality of electrical terminals configured for being respectively coupled to a plurality of stimulation electrodes; stimulation output circuitry configured for being selectively activated during the stimulation state to output a plurality of stimulation pulses to the plurality of electrical terminals; electromagnetic protection circuitry configured for being selectively activated during the EMI protection state to prevent at least a portion of an electrical current induced on at least one of the electrical terminals by an electromagnetic field from entering the stimulation output circuitry; and a controller configured for automatically defaulting the neurostimulation device from the stimulation state to the EMI protection state in response to a non-user initiated event selected from the group consisting of a drop in a power supply output below a predetermined level and a termination of a system test.
