TYPICAL APPLICATION

APPLICATIONS
DESCRIPTION
5A Integrated
Hot Swap Controller
The LTC4219 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 LTC4219 provides separate inrush current control
and a 10% accurate 5.6A 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 amplies the sense
resistor voltage for ground referenced current sensing
and a MOSFET temperature monitor output. Thermal limit
and power good monitoring are also provided. The power
good detection level and foldback current limit prole are
internally preset for 5V (LTC4219-5) and 12V (LTC4219-12)
applications.
