Winziger USB-PowerPath-Manager ist überspannungsfest bis 60V

(PresseBox) (Ismaning, )
Linear Technology Corporation präsentiert den LTC4090, einen autonomen, linearen PowerPath™-Manager mit "Ideale-Diode"-Controller und autonomem Hochspannungs-Akkulader für tragbare USB-Geräte. Die auf einer Schaltregler-Topologie basierende Eingangsschaltung ermöglicht Laden mit hohem Wirkungsgrad, eignet sich zum Betrieb an Spannungsquellen bis 38V – beispielsweise geregelte oder ungeregelte Netzadapter, FireWire-Schnittstellen oder Auto-Bordnetze – und ist bis 60V überspannungsfest. Darüber hinaus akzeptiert der Chip aber auch Niederspannungsquellen wie z. B. 5V-Netzadapter, USB-Schnittstellen oder Einzellen-Li-Ion/Polymer-Akkus. Der LTC4090 enthält einen linearen PowerPath-Controller, der das Endprodukt mit Betriebsspannung versorgt, während er dessen Einzellen-Lithium-Akku aus der USB-Schnittstelle oder einem Netzadapter auflädt. Entsprechend den USB-Spezifikationen für die Strombelastbarkeit reduziert der LTC4090 bei qghvhbfycg Ezaghvcuaocrlqu eaafspszwof fji Lojn-Swvbkiech.
