A method for controlling an implantable medical device is disclosed. In one embodiment, a voltage of a power source within the implantable medical device is monitored. If this voltage is above a first threshold, the implantable medical device enables the following functions: it listens for a first type of telemetry from a first external component; it listens for a second type of telemetry from an external charging component; and it provides stimulation to device electrodes using the power source. By contrast, if the power source voltage falls below the first threshold, the implant discontinues listening for the first type of telemetry from the first external component and discontinues providing stimulation to device electrodes using the power source, but continues to listen for the second type of telemetry.

What is claimed is: 1. A method for controlling an implantable medical device, comprising: monitoring a voltage of a power source within the implantable medical device; if the voltage is above a first threshold, enabling the following functions: listening for a first type of telemetry from a first external component; listening for a second type of telemetry from an external charging component, wherein the external charging component is used to wirelessly charge the power source; and providing stimulation to device electrodes using the power source; and if the voltage falls below the first threshold, discontinuing listening for the first type of telemetry from the first external component and discontinuing providing stimulation to device electrodes using the power source, while continuing listening for the second type of telemetry. 2. The method of claim 1, wherein the first telemetry type comprises Frequency Shift Keying (FSK), and wherein the second telemetry type comprises On/Off Keying (OOK). 3. The method of claim 1, wherein the first threshold is stored in a first register in the implantable medical device. 4. The method of claim 1, further comprising if the voltage later exceeds the first threshold after falling below the first threshold, resuming listening for the first telemetry type and resuming providing stimulation to device electrodes using the power source. 5. The method of claim 1, further comprising: if the voltage falls below the first threshold, and later falls below a second threshold lower than the first threshold, discontinuing listening for the first telemetry type and discontinuing providing stimulation to device electrodes using the power source until the device is recharged. 6. The method of claim 1, wherein the power source comprises a lithium ion battery. 7. The method of claim 1, wherein the first external component and the external charging component are the same component. 8. A method for controlling an implantable medical device, comprising: monitoring a voltage of a power source within the implantable medical device; if the voltage is above a first threshold, enabling the following functions: listening for a first type of telemetry from a first external component, wherein the first external component is used to program stimulation parameters for the implantable medical device; listening for a second type of telemetry from an external charging component, wherein the external charging component is used to wirelessly charge the power source; and providing stimulation to device electrodes using the power source and in accordance with the stimulation parameters; and if the voltage falls below the first threshold, discontinuing listening for the first telemetry type and discontinuing providing stimulation to device electrodes using the power source, while continuing listening for the second telemetry type so that the power source can be recharged. 9. The method of claim 8, wherein the first telemetry type comprises Frequency Shift Keying (FSK), and wherein the second telemetry type comprises On/Off Keying (OOK). 10. The method of claim 8, wherein the first threshold is stored in a first register in the implantable medical device. 11. The method of claim 8, further comprising if the voltage later exceeds the first threshold after falling below the first threshold, resuming listening for the first telemetry type and resuming providing stimulation to device electrodes using the power source. 12. The method of claim 8, further comprising: if the voltage falls below the first threshold, and later falls below a second threshold lower than the first threshold, discontinuing listening for the first telemetry type and discontinuing providing stimulation to device electrodes using the power source until the device is recharged. 13. The method of claim 8, wherein the power source comprises a lithium ion battery. 14. A method for controlling an implantable medical device that provides therapy to a patient, comprising: monitoring a voltage of a power source within the implantable medical device; if the voltage is above a first threshold, enabling the following functions: listening for a first type of telemetry from a first external component; listening for a second type of telemetry from an external charging component, wherein the external charging component is used to wirelessly charge the power source; and providing therapy to the patient; and if the voltage falls below the first threshold, discontinuing listening for the first type of telemetry from the first external component and discontinuing providing therapy to the patient, while continuing listening for the second type of telemetry. 15. The method of claim 14, wherein the first telemetry type comprises Frequency Shift Keying (FSK), and wherein the second telemetry type comprises On/Off Keying (OOK). 16. The method of claim 14, wherein the first threshold is stored in a first register in the implantable medical device. 17. The method of claim 14, further comprising if the voltage later exceeds the first threshold after falling below the first threshold, resuming listening for the first telemetry type and resuming providing therapy to the patient. 18. The method of claim 14, further comprising: if the voltage falls below the first threshold, and later falls below a second threshold lower than the first threshold, discontinuing listening for the first telemetry type and discontinuing providing therapy to the patient until the device is recharged. 19. The method of claim 14, wherein the power source comprises a lithium ion battery. 20. The method of claim 14, wherein the first external component and the external charging component are the same component.
