ADM1070 - 48 V Hot Swap Controller in SOT-23 with Linear Current Limiting

The ADM1070 -48 V hot swap controller is designed for central office applications. The space-saving SOT-23 package occupies just 25% of the board area of an 8 pin SOIC solution. The device utilizes a linear current control method and protects the supply from in-rush currents (board insertion) and short circuits (board failure). The ADM1070 also provides protection during voltage steps associated with card re-seating. It current limits under all conditions.

Applications
  • Central Office Switching
  • -48 V Distributed Power Systems
  • Negative Power Supply Control
Features and Benefits
  • Allows safe board insertion and removal from a live -48V backplane
  • Operates from a typical -36V to -80V
  • Tolerates transients up to -200V (limited by external components)
  • Accurate programmable linear current limit for inrush control
  • Programmable time-out in current limit
  • Auto-restart after current limit time-out
  • Shutdown after 7 consecutive auto-restarts
  • Default timing provided with no osc cap
  • Single pin under/overvoltage detection
  • Programmable under/overvoltage time filter
  • Small 6-pin SOT-23 package
  • See datasheet for additional information
