The LTC4260 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.

The device features adjustable analog foldback current limit with latch off or automatic restart after the LTC4260 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.

Applications

  • Electronic Circuit Breakers
  • Live Board Insertion
  • Computers, Servers
