GENERAL DESCRIPTION

The ADM1075 is a full feature, negative voltage, hot swap controller with constant power foldback and high accuracy digital current and voltage measurement that allows boards to be safely inserted and removed from a live ?48 V backplane. The part provides precise and robust current limiting and protection against both transient and nontransient short circuits and overvoltage and undervoltage conditions. The ADM1075 typically operates from a negative voltage of ?35 V to ?80 V and, due to shunt regulation, has excellent voltage transient immunity. The operating range of the part is flexible due to the shunt regulator, and the part can be powered directly by a 10 V rail to save shunt power dissipation (see the Powering the ADM1075 section for more details).
