Method and circuit for hot swap protection

   
   

A hot swap protection circuit (40) for an integrated circuit being plugged into a powered-up system includes a first circuit (10) for detecting a hot swap condition, a second circuit (20) coupled to the first circuit for preventing a pn junction diode (52) in a pull-up transistor (32) from going into a forward bias condition, and a third circuit (30) coupled to the first and second circuits for preventing the pull-up transistor from turning on during the hot swap condition.

Горячая цепь предохранения от обмена (40) для интегрированной цепи будучи затыканной в privedennuh-vverx в действие систему вклюает первую цепь (10) для обнаруживать горячее состояние обмена, вторая цепь (20) соединенная к первой цепи для предотвращать диод соединения (52) pn в vyt4givaet-vverx транзистор (32) от идти в условие forward bias, и третья цепь (30) соединенная к первым и вторым цепям для предотвращать vyt4givaet-vverx транзистор от поворачивать дальше во время горячего состояния обмена.
