Overview

The LTC4217CDHC 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. A dedicated 12V version (LTC4217-12) contains preset 12V specific thresholds, while the standard LTC4217CDHC allows adjustable thresholds.

The LTC4217CDHC provides separate inrush current control and a 5% accurate 2A 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, overvoltage, undervoltage and power good monitoring are also provided. For a 5A pin compatible version, see LTC4232.
