A switch control circuit and a battery pack including the same are disclosed. The switch control circuit can include a first controller outputting a first control signal for controlling a driver, and a second controller configured to detect a fault of the first controller and to output a second control signal in response to detecting the fault of the first controller. The switch control circuit can further include first to third buffers each outputting an output signal corresponding to the first control signal or changing an output terminal of each buffer to an open state in response to the second control signal. The switch control circuit can further include a holding circuit holding a previous state of an input signal of the third buffer and a switch circuit transferring the output signal of the second buffer or the third buffer to the driver in response to the second control signal.
