nn Available in 16-Lead 5mm Г— 3mm DFN Package The LTCВ®4232 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. nn 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 …
