n 12-Lead MSOP and 3mm Г— 3mm QFN Packages The LTCВ®4231 is a micropower Hot Swapв„ў controller that
allows safe circuit board insertion and removal from a live
power supply. An internal high side switch driver controls
the gate of an external N-channel MOSFET. Back-to-back
MOSFETs can be used for reverse supply protection down
to –40V. n Applications n n n Battery Powered Equipment
