The ADM1270 is a current-limiting controller that providesinrush current limiting and overcurrent protection for modularor battery-powered systems. When circuit boards are insertedinto a live backplane, discharged supply bypass capacitors drawlarge transient currents from the backplane power bus as theycharge. These transient currents can cause permanent damageto connector pins, as well as dips on the backplane supply thatcan reset other boards in the system.The ADM1270 is designed to control the inrush current, whenpowering on the system, via an external P-channel field effecttransistor (FET).To protect the system from a reverse polarity input supply, thereis a provision made to control an additional external P-channelFET. This feature prevents reverse current flow in case of a reversepolarity connection, which can damage the load or the ADM1270.The ADM1270 is available in a 3 mm ? 3 mm, 16-lead LFCSP anda 16-lead QSOP.
