Product Summary

The LT1641-1CS8 is an 8-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 a programmable rate. A high side switch driver controls an N-channel gate for supply voltages ranging from 9V to 80V. The chips feature a programmable analog foldback current limit circuit. If the chips remain in current limit for more than a programmable time, the N-channel pass transistor is either latched off LT1641-1CS8 or is set to automatically restart after a time-out delay.
