LTC4370  
Two-Supply Diode-OR  
Current Balancing Controller  
FeaTures  
DescripTion  
The LTC®4370 is a two-supply current sharing controller  
which incorporates MOSFET ideal diodes. The diodes  
block reverse and shoot-through currents during start-up  
and fault conditions. Their forward voltage is adjusted to  
share the load currents between supplies. Unlike other  
sharing methods, neither a share bus nor trim pins on  
the supply are required.

Enable Inputs  
The maximum MOSFET voltage drop can be set with a  
resistor. A fast gate turn-on reduces the load voltage  
droop during supply switchover. If the input supply fails  
or is shorted, a fast turn-off minimizes reverse current  
transients.

Status outputs indicate whether the MOSFETs are on or  
off. The load sharing function can be disabled to turn the
