1. A charge device, comprising:
- a Low Drop Out (LDO) configured to convert a reference voltage to a detection voltage for detecting an abnormal charge request;
a switch configured to disconnect or connect a charge path with an external device; and
a processor, the processor is configured to;
disconnect the charge path with the external device by control of the switch in a non-charging operation,determine a normal voltage based on the detection voltage in a charging operation,determine whether a charge request is the abnormal charge request based on whether the normal voltage is changed,control to maintain disconnection of the charge path by the switch, in response to determining that the charge request is the abnormal charge request, andcontrol to connect of the charge path by the switch, in response to determining that the charge request is a normal charge request.

Abstract
A charge device for controlling an abnormal charge request is provided. The charge device includes a controller that interrupts a charge path, when power is applied and that determines whether a charge request is an abnormal charge request through a detour charge path and that controls to maintain interruption of the charge path, if the charge request is an abnormal charge request. The controller may be further configured to interrupt the detour charge path, in response to determining that the charge request is a normal charge request; connect the charge path; and supply a charge current to the charge path.

10. A method of controlling charge in a charge device, the method comprising:
-
disconnecting a charge path, with an external device by control of a switch of the charge device in a non-charging operation; determining a normal voltage based on a detection voltage in a charging operation; determining whether a charge request is an abnormal charge request based on whether the normal voltage is changed; maintaining disconnection of the charge path by the switch in response to determining that the charge request is an abnormal charge request; and connecting the charge path by the switch, in response to determining that the charge request is a normal charge request. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable medium comprising instructions, that when executed by at least one processor, cause a charge device to:
-
disconnect a charge path, with an external device by control of a switch of the charge device in a non-charging operation; determine a normal voltage based on a detection voltage in a charging operation; determine whether a charge request is an abnormal charge request based on whether the normal voltage is changed; maintain disconnection of the charge path by the switch in response to determining that the charge request is an abnormal charge request; and connect the charge path by the switch, in response to determining that the charge request is a normal charge request. - View Dependent Claims (18, 19, 20)
