The LTC4245 Hot Swap™ controller allows a board to be safely inserted and removed from a live backplane in multiple supply systems such as CompactPCI and PCI Express. Using four external N-channel pass transistors, the board supply voltages can be ramped up at an adjustable rate and in any desired sequence. An I2C interface and on-board ADC allow monitoring of board current, voltage and fault status for each supply.
The device features adjustable dI/dt controlled soft start and foldback limited inrush current. A dual-level timed circuit breaker and fast current limit protect each supply against overcurrent faults. A power good input with timeout allows a downstream supply monitor to disconnect the board supplies. The device can be configured to function without a –12V supply or with an extra 3.3V supply instead of a 5V supply.
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.
Applications
- Live Board Insertion
- CompactPCI, CompactPCI Express, CompactTCA, PCI Express Systems
