DESCRIPTION
Compact Dual Low
Voltage Hot Swap Controller
The LTC4224 Dual Low Voltage Hot Swap controller
allows a board to be safely inserted and removed from a
live backplane. It controls two supplies with external N-
channel MOSFETs and operates with one supply as low
as 1V provided the other supply is 2.7V or greater. The
LTC4224 can ramp up the supplies in any order and at
adjustable ramp rates. To minimize the number of external
components and PCB area, the gate capacitor is optional,
all timing delays are generated internally, and the ON pins
have integrated pull-up currents.
Protection against overcurrent faults is provided by a fast-
acting current limit and timed circuit breakers. A FAULT pin
signals overcurrent faults. The LTC4224-1 remains off after
a fault, while the LTC4224-2 automatically tries to apply
power again after a four second cool-down period.
