Description
General part information
LTC4215-1LTC4215-3 Series
The LTC4215-1/LTC4215-3 Hot Swap™controllers allow a board to be safely inserted and removed from a live backplane. Using an external N-channel pass transistor, board supplyvoltage and inrush current are ramped up at an adjustable rate. An I2C interface and on-board ADC allow for monitoring of load current, voltage and fault status.The device features adjustable foldback current limit and a soft-start pin that sets the dI/dt of the inrush current. An I2C interface may configure the part to latch-off or automatically restart after the LTC4215-1/LTC4215-3 detect a current limit fault.The controller has additional features to interrupt the host when a fault has occurred, provide three general purpose outputs, notify when output power is good, detect insertion of a load card, and power-up either automatically upon insertion or wait for an I2C command to turn on.The LTC4215-1 has a 20μs circuit breaker filter for applications that require a fast fault response time. The LTC4215-3 has an extended 420μs circuit breaker filter for applications where supply transients may exceed 20μs.Circuit Breaker TimeoutGeneral Purpose OutputsLTC421520μs1LTC4215-120μs3LTC4215-2420μs1LTC4215-3420μs3ApplicationsLive Board InsertionElectronic Circuit BreakersComputers, ServersPlatform Management
