  • Current sensing protection device for sensing whether current sensing element occurs short phenomenon
    Patent number: 11831145
    Abstract: A current sense short protection circuit includes a switch unit, a current sensing unit, a detection circuit and a short detection module. The first terminal of the switch unit receives a first voltage. The control terminal of the switch unit receives a control signal. The first terminal of the current sensing unit is coupled to the second terminal of the switch unit. The second terminal of the current sensing unit receives a second voltage. The detection unit receives the second voltage and a third voltage provided by the first terminal of the current sensing unit, and generates a detection signal according to the second voltage and the third voltage. The short detection module receives the first voltage, the second voltage and the detection signal, and generates a short detection signal according to the first voltage, the second voltage and the detection signal.
