Abstract

This publication describes a passive electrical detent switch for power supplies that may or may not be provided by an external source. In this context, an electrical detent is in some ways analogous to the well-known mechanical detent that resists or arrests mechanical movement to some extent. Similarly, a passive electrical detent holds a voltage at a certain level until overridden or disabled. In the case that the supply is provided externally, the external supply may override and disable the detent and drive the supply to its desired value. In the case that the supply is generated internally, the detent will hold the supply in a known and driven state until the active shorting switch can be enabled.
