LTC4224-1/LTC4224-2  
Compact Dual Low  
Voltage Hot Swap Controller  
FEATURES  
DESCRIPTION  
The LTC®4224 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.
