  • Accurate programmable linear current limit for inrush control
  • 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

Product Details

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.
