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 * Hot Board Insertion * Electronic Circuit Breaker * High Availability Servers * Programmable Current Limiting Circuit * –48 V Power Supply Modules * 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
