An ESD module is presented. The ESD module includes an ESD circuit and a latch-up (LU) control circuit. The ESD circuit has a pad terminal and a low power source terminal. The LU control circuit includes a first LU terminal coupled to a high power source and an LU output terminal coupled to the ESD circuit. The ESD module has first and second operating modes. In the first operating mode, the LU control circuit is deactivated and the ESD circuit has a first triggering current Iwhich is less than 100 mA. In the second operating mode, the LU control circuit is activated and the ESD circuit has a second triggering current Iwhich is greater than 100 mA.
