â ???? 48 V热插拔控制器和数字 â48 V Hot Swap Controller and Digital
The is an evaluation board for ADM1075 devices. This 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 -48V backplane. The part provides precise and robust current limiting and protection against both transient and nontransient short circuits and overvoltage and undervoltage conditions. The operating range of the part is flexible due to the shunt regulator, and the part can be powered directly by a 10V rail to save shunt power dissipation. A full-scale current limit of 25mV or 50mV can be selected by choosing the appropriate model.
