GENERAL DESCRIPTION
The ADM1270 is a current-limiting controller that provides inrush current limiting and overcurrent protection for modular or battery-powered systems. When circuit boards are inserted into a live backplane, discharged supply bypass capacitors draw large transient currents from the backplane power bus as they charge. These transient currents can cause permanent damage to connector pins, as well as dips on the backplane supply that can reset other boards in the system.

FEATURES
   Controls supply voltages from 4 V to 60 V
   Gate drive for low voltage drop reverse supply protection
   Gate drive for P-channel FETs
   Inrush current limiting control
   Adjustable current limit
   Foldback current limiting
   Automatic retry or latch-off on current fault
   Programmable current-limit timer for safe operating area (SOA)
   Power-good and fault outputs
   Analog undervoltage (UV) and overvoltage (OV) protection
   16-lead, 3 mm × 3 mm LFCSP
   16-lead QSOP

APPLICATIONS
   Industrial modules
   Battery-powered/portable instrumentation
