Abstract

Un dispositivo portátil electrónico tiene una batería para proporcionar energía para operar el dispositivo, un conector que incluye un pm de fuente de alimentación para acoplarse a una fuente de alimentación externa, y un administrador de energía que tiene un circuito cargador de batería que extrae energía a través del pm de fuente de alimentación para cargar la batería. El administrador de energía tiene un circuito de control por retroalimentación de límite de corriente que limita la corriente extraída de acuerdo con una corriente nominal de salida predeterminada de la fuente de alimentación externa, El administrador de energía automáticamente cambia el comportamiento de su circuito de control para estabilizar la operación de la fuente de alimentación externa acoplada. Otras modalidades también se describen y reclaman.
