The LTC4232 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 LTC4232 provides separate inrush current control and a 10% accurate 5A 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 2A pin compatible version, see LTC4217.The LTC4232-1 (separate data sheet) allows faster turn-on than the LTC4232 by providing 16ms debounce delay and external control of the GATE ramp rate.Applications RAID Systems, Solid State Drives Server I/O Cards Industrial
