5A Integrated Hot Swap
Controller
The LTC
?/DIV>
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 resis-
tor 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 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.
