Abstract
A system for monitoring and controlling power demands in devices with DC power supplies is disclosed. In response to a detected decline in voltage levels, the device reduces the power demands of the device, in one or more stages, before powering down entirely. This approach has application to battery powered devices, particularly for medical applications such as cochlear implants.
