Abstract
An ESD protecting circuit, which comprises: a first voltage pad; a second voltage pad; an I/O pad; a first ESD protecting module, comprising a first terminal coupled to the first voltage pad; a MOS transistor, comprising a first terminal coupled to a second terminal of the first ESD protecting module, comprising a second terminal coupled to the I/O pad, and comprising a control terminal for receiving a control signal; a second ESD protecting module, comprising a first terminal coupled to the first terminal of the MOS transistor, and comprising a second terminal coupled to the second voltage pad; and an ESD detecting circuit, for generating the control signal to control the MOS transistor to be conductive when an ESD voltage is detected and to control the MOS transistor to be nonconductive when the ESD voltage is not detected.
