More Information
Summary:A latch-up protection device is provided. The latch-up protection device includes a first transistor, a detection module, and a processing module. The first transistor includes a first source/drain coupled to a pad, a body and a second source/drain coupled to a first voltage, and a gate. The detection module is adapted for detecting a terminal voltage between the first source/drain and the second source/drain of the first transistor, and generating a first signal when the terminal voltage is greater than a trigger voltage. The processing module is coupled between the detection module and the gate of the first transistor, for conducting a logic processing to the first signal, and generating an enable signal to the gate of the first transistor to conduct the first transistor.
