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 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 Timeout | General Purpose Outputs | |
| LTC4215 | 20μs | 1 |
| LTC4215-1 | 20μs | 3 |
| LTC4215-2 | 420μs | 1 |
| LTC4215-3 | 420μs | 3 |
