Richardson RFPD Power Management IC ADM1075-1ARUZ

The ADM1075 is a full feature, negative voltage, hot swap control-ler 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
