DescripTion
2A Integrated Hot Swap
Controller
The LTC4217 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
Swapcontroller,powerMOSFETandcurrentsenseresistor
in a single package for small form factor applications. A
dedicated 12V version (LTC4217-12) contains preset 12V
specific thresholds, while the standard LTC4217 allows
adjustable thresholds.
The LTC4217 provides separate inrush current control
and a 5% accurate 2A current limit with foldback cur-
rent 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.
