LTC1642 - Hot Swap Controller
LTC1642 - Hot Swap Controller - Linear Technology（凌力尔特）
The LTC1642 is a 16-pin Hot SwapTM controller that allows a board to be safely inserted and removed from a live backplane. Using an external N-Channel pass transistor, the board supply voltage can be ramped up at an adjustable rate. A high side switch driver controls the N-Channel gate for supply voltages above 2.97V.
The SENSE pin allows foldback limiting of the load current, with circuit breaker action after an adjustable delay time. The delay allows the part to power-up in current limit. The CRWBR output can be used to trigger an SCR for crowbar protection of the load if the input supply exceeds an adjustable threshold. The RESET output can generate a system reset with adjustable delay when the supply voltage falls below an adjustable threshold. The ON pin cycles the board power. The LTC1642 is available in the 16-pin SSOP package.
