Dual Ideal Diode and  
Hot Swap Controller  
FeaTures  
DescripTion  
The LTC®4228 offers ideal diode and Hot Swap™ functions  
for two power rails by controlling two external N-channel  
MOSFETs in each rail. MOSFETs acting as ideal diodes re-  
place two high power Schottky diodes and the associated  
heat sinks, saving power and board area. Hot Swap control  
MOSFETs allow boards to be safely inserted and removed  
fromalivebackplanebylimitinginrushcurrent.Thesupply  
output is also protected against short-circuit faults with a  
fast acting current limit and internal timed circuit breaker.

The LTC4228 regulates the forward voltage drop across  
theexternalMOSFETsandsenseresistortoensuresmooth  
current transfer from one supply to the other without  
oscillation. The ideal diodes turn on quickly to reduce  
the load voltage droop during supply switch-over. If the  
input supply fails or is shorted, a fast turn-off minimizes  
reverse-current transients.
