- See datasheet for additional information
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
