Hot-Swap-Controller mit integrierter Leistungsüberwachung und Fehlersignalisierung schützt zwei Stromversorgungen

(PresseBox) (Milpitas, California (USA), )
Linear Technology Corporation präsentiert den Zweikanal-Hot-Swap(TM) -Controller LTC4222 zum Schutz von Baugruppen mit mehreren Lastbetriebsspannungen zwischen 2,9V und 29V. Beim Einstecken einer Karte in einen Rückwandbus kann ein hoher Einschaltstrom fließen, der einen Störimpuls auf der Betriebsspannung hervorruft, welcher eine Fehlfunktion anderer Karten verursachen kann. Der LTC4222 begrenzt den Einschaltstrom beim Hochfahren durch entsprechende Ansteuerung externer n-Kanal-MOSFETs und ermöglicht dadurch ein sicheres Einstecken und Herausnehmen von Karten in bzw. aus einem unter Spannung stehenden Rückwandbus mit zwei Betriebsspannungen. Eine I2C-Schnittstelle und ein integrierter 10-bit-A/D-Wandler ermöglichen es, wichtige Informationen wie z. B. Kartenströme, Spannungen oder Fehlerzustände abzufragen und anhand dieser Informationen
