Abstract:

An ESD protection circuit for a switching power converter which includes a high-side switching element connected between a supply voltage and the switching node, and a low-side switching element connected between the switching node and a common node. A current conduction path couples an ESD event that occurs on the switching node to an ESD sense node, and an ESD sensing circuit coupled to the sense node generates a trigger signal when an ESD event is sensed. A first logic gate keeps the high-side switching element off when the trigger signal indicates the sensing of an ESD event, and a second logic gate causes the low-side switching element to turn on when an ESD event is sensed such that the low-side switching element provides a conductive discharge path between the switching node and common node.

Abstract:

Systems, methods, apparatus, and computer program products provide user-defined messages. In one embodiment, user-defined messaging configurations can be defined. Then, a record queue can be monitored for the entry of new records. New records can be evaluated to determine whether they are associated with user-defined messaging configurations. For the records so associated, reports defined in the user-defined messaging configurations can be requested and used to create user-defined messages.
