Abstract
Systems and methods for voltage ramp-up protection. In an illustrative, non-limiting embodiment, a method may include monitoring at least one of a first node or a second node, the first node configured to receive a first voltage greater than a second voltage present at a second node, and, in response to a slew rate of the first voltage creating a sneak condition between the first node and the second node, counteracting the sneak condition. For example, the sneak condition may favor an excess current to flow from the first node to the second node. In some cases, counteracting the sneak condition may include maintaining the second voltage below at or below a predetermined value.
