LTC4260CGN#PBF

LTC4260 is a Hot Swap™ controller 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. An I²C interface and onboard ADC allow monitoring of board current, voltage and fault status. This device features adjustable analogue foldback current limit with latch off or automatic restart after the device remains in current limit beyond an adjustable time-out delay. The controller has additional features to interrupt the host when a fault has occurred, notify when output power is good, detect insertion of a load card and power-up in either the on or off state. It is widely used in application such as electronic circuit breakers, live board insertion, computers, servers etc.
