FEATURES  
DESCRIPTIO  
Hot SwapTM Controller for Positive  
The LT®4220 16-pin dual voltage Hot Swap controller  
allows a board to be safely inserted and removed from a  
live backplane. The device operates with any combination  
of 2.7V to 16.5V and –2.7V to –16.5V supplies. Using two  
external N-channel pass transistors, the board supply  
voltages can be ramped up at an adjustable rate. A select-  
able tracking mode allows dual supply tracking control for  
ramping the positive and negative supplies together.  
and Negative Supplies  
Supply Tracking Mode  
±2.7V to ±16.5V Operation  
Analog Current Limit with Foldback  
Allows Safe Board Insertion and Removal  
from a Live Backplane  
Open-Collector Power Good Comparators  
Automatic Retry or Latchoff After a Current Fault  
The LT4220 features foldback current limit and latches off  
both gates if either supply remains in current limit longer  
than an adjustable time period. The IC can be configured  
for automatic restart after a delay set by the same timer.  
Dual Undervoltage Lockout Comparator Inputs
