Descrizione

Traduzione AI

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 supply voltage and inrush current are ramped up at an adjustable rate. An I²C interface and onboard 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.
