DESCRIPTION
The LTC®4217 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 specifi c thresholds, while the standard LTC4217 allows adjustable thresholds.
