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

Product Description

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

    • 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
