1. A system comprising:
an implantable device comprising a battery, and a power manager, wherein the implantable device operates according to an operation mode, wherein the operation mode includes a power saving mode in which the implantable device is in a sleep state and an active mode in which the implantable device is in an operating state; and
a wake-up device comprising:
a real-time clock (RTC) connected directly to the implantable device and configured to count a time value for switching the operation mode between the power saving mode and the active mode; and
a wireless power transfer device configured to sense whether a wireless power is wirelessly supplied from an external power source separate from the battery, switch the operation mode as the wireless power is wirelessly supplied from the external power source, and turn on an enable signal of the power manager to operate in the active mode based on a result of the sensing, irrespective of whether a count value of the time value has expired.
