LTC4222  
Dual Hot Swap Controller

with I C Compatible  
Monitoring  
FEATURES  
DESCRIPTION  
The LTC®4222 Hot Swap™ controller allows two power  
paths to be safely inserted and removed from a live back-  
plane. Using external N-channel pass transistors, board  
supply voltages and inrush currents are ramped up at an  
adjustable rate. An I C interface and onboard ADC allows  
for monitoring of current, voltage and fault status for  
each channel.

Input Overvoltage/Undervoltage Protection  
The device features adjustable, analog, foldback current  
limit circuits and a Soft-Start circuit that sets the dI/dt of  
the inrush currents. An I C interface may configure the  
part to latch off or automatically restart after the LTC4222  
detects a fault on either channel.
