Abstract
A mobile terminal uses a battery as a power source, and has a battery protection circuit for protecting the battery. A control circuit of the mobile terminal detects a voltage value or a current value of a predetermined electronic circuit such as a power amplifier, and determines whether or not an abnormal state is present. Upon determination that the power amplifier is in an abnormal state, the control circuit short-circuits the battery to operate the battery protection circuit. As a result, the supplying of a power supply current to the power amplifier is stopped to eliminate the abnormal state.
