The LT4256-3 is a high voltage Hot Swapâ„¢ controller that allows a board to be safely inserted and removed from a live backplane. An internal driver controls the high side N-channel MOSFET gate for supply voltages ranging from 10.8V to 80V. The part features an open-circuit detect (OPEN) output that indicates abnormally low load current conditions.The LT4256-3 also features an adjustable analog foldback current limit. If the supply remains in current limit for more than a programmable time, the N-channel MOSFET shuts off, the PWRGD output asserts low and the LT4256-3 either automatically restarts after a time-out delay or latches off until the UV pin is cycled low (depending on the status of the RETRY pin).The PWRGD output indicates when the output voltage rises above a programmed level. An external resistor string from VCC provides programmable undervoltage and overvoltage protection.The LT4256-3 is available in a 16-lead SSOP package. Retry / Latch Off Features Package LT4256-1 Latch Off UV SO-8 LT4256-2 Retry UV SO-8 LT4256-3 Latch Off or Retry UV/OV, Open Circuit Detect SSOP-16
