Abstract
A power transmission circuit includes a first transmission transistor, a second transmission transistor, and a first control circuit. A first terminal of the first transmission transistor is used as a power input terminal of the power transmission circuit. A second terminal of the first transmission transistor is coupled to a first node. A control terminal of the first transmission transistor is coupled to a control node. A first terminal of the second transmission transistor is used as a power output terminal of the power transmission circuit. A second terminal of the second transmission transistor is coupled to the first node. When a voltage of the power output terminal is greater than or equal to a voltage of the power input terminal, the first control circuit outputs a first voltage to the control node, to turn off the first transmission transistor and the second transmission transistor.
