Abstract
Methods, apparatus, systems and articles of manufacture are disclosed for preventing undesired triggering of short circuit or over current protection. An example apparatus includes an output terminal; a voltage detection device coupled to a voltage detection input terminal and the output terminal and including a voltage detection output coupled to a logic gate first input terminal; a pulse extender coupled between a logic gate output and a selecting node; a multiplexer coupled to the selecting node and configured to be coupled to a first protection circuit, a second protection circuit, and a driver; and a switch coupled between an input terminal and the output terminal and including a switch gate terminal coupled to the driver.
