1. A controller comprising:
a plurality of sub-circuits; and
a processor configured to:
control the controller to operate in an activation mode for the controller using a current with a current value greater than or equal to an activation current, in response to receiving a command from outside;
determine whether activation conditions of the plurality of sub-circuits are satisfied during the activation mode, each of the activation conditions indicating whether a corresponding sub-circuit requires a current with a current value greater than or equal to the activation current; and
control the controller to operate in a low-power mode for the controller using a current with a current value lower than the activation current value, when the activation conditions of all of the plurality of sub-circuits are not satisfied and a predetermined time has elapsed from an initiation of the activation mode.
