Abstract
A protection circuit includes a first input, an over-voltage protector, an over-current protector, and a first output connected in series in that order. The first input is configured for receiving a power source. The first output is configured for outputting a voltage of the power source to a load circuit. The over-voltage protector is configured to cut off an electrical connection between the first input and the first output under the condition that a voltage value of the power source is greater than a predetermined voltage value. The over-current protector is configured to cut off an electrical connection between the first input and the first output under the condition that a current value from the first output is greater than a predetermined current value.
