nn Available in a 38-Pin (5mm Г— 9mm) QFN Package The LTCВ®4234 is an integrated solution for Hot Swapв„ў
applications that allows a board to be safely inserted and
removed from a live backplane. The part integrates a
HotВ Swap controller, power MOSFET and current sense
resistor in a single package for small form factor applications. The MOSFET Safe Operating Area is production tested
and guaranteed for the stresses in Hot Swap applications. nn The LTC4234 provides separate inrush current control …
