DETECTING FAULTS IN HOT-SWAP APPLICATIONS

摘要

A circuit is provided for detecting a fault condition in a system that supplies power from an input node to an output node and has at least one switch coupled between the input node and the output node. The fault detection circuit is configured to indicate a fault condition when the switch is commanded to turn on and at least one of the following conditions is detected: A voltage across the switch exceeds a predetermined value or a value of a switch control signal causes the switch to turn on. in case of insufficient. A fault condition is indicated only when the detected condition exists for a predetermined period of time.
