Description
AI
The LTC4219 is an integrated solution for Hot Swap applications that allows a board to be safely inserted and removed from a live backplane. The part integrates a Hot Swap controller, power MOSFET and current sense resistor in a single package for small form factor applications.The LTC4219 provides separate inrush current control and a 10% accurate 5.6A current limit with foldback current limiting. The current limit threshold can be adjusted dynamically using an external pin. Additional features include a current monitor output that amplifies the sense resistor voltage for ground referenced current sensing and a MOSFET temperature monitor output. Thermal limit and power good monitoring are also provided. The power good detection level and foldback current limit profile are internally preset for 5V (LTC4219-5) and 12V (LTC4219-12) applications.ApplicationsRAID SystemsServer I/O CardsIndustrial
