LTC4224-1/LTC4224-2 pact Dual Low Voltage Hot Swap Controller DESCRIPTION
The LTC®4224 Dual Low Voltage Hot Swap™ controller allows a board to be safely inserted and removed from a live backplane. It controls two supplies with external Nchannel MOSFETs and operates with one supply as low as 1V provided the other supply is 2.7V or greater. The LTC4224 can ramp up the supplies in any order and at adjustable ramp rates. To minimize the number of external ponents and PCB area, the gate capacitor is optional, all timing delays are generated internally, and the ON pins have integrated pull-up currents. Protection against overcurrent faults is provided by a fastacting...
