LTC4223-1 Datasheet (Linear Technology) - Dual Supply Hot Swap Controller

LTC4223-1, Dual Supply Hot Swap Controller

The LTC®4223 positive voltage Hot SwapTM controller allows a board to be safely inserted and removed from a live AMC or MicroTCA backplane.

It controls the main 12V supply with an external N-channel MOSFET and the 3.3V auxiliary supply with an integrated switch.

The 12V output ramp rate is adjustabl
