TYPICAL APPLICATION
DESCRIPTION
Hot Swap Controller with
I2C Compatible Monitoring
The LTC
4215/LTC4215-2 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 congure the part to latch off or
automatically restart after the LTC4215 detects a current
limit fault.
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 either
automatically upon insertion or wait for an I2C command
to turn on.
The LTC4215 has a 20μs circuit breaker lter for applica-
tions that require a fast fault response time and it defaults
to latchoff after an overcurrent fault. The LTC4215-2 has
an extended 420μs circuit breaker lter for applications
where supply transients may exceed 20μs and it defaults
to restart automatically after an overcurrent fault.
