Abstract
Systems and methods of suppressing latchup. In accordance with a first embodiment of the present invention a latchup suppression system comprises a voltage comparator for comparing a voltage applied to a body terminal of a semiconductor device to a reference voltage. The voltage comparator is also for controlling a selective coupling mechanism. The selective coupling mechanism is for selectively coupling the body terminal to a respective power supply. The latchup suppressing system is preferably independent of a voltage supply for applying a voltage to the body terminal.
