Description  
The INT100 half-bridge driver IC provides gate drive for  
externallow-sideandhigh-sideMOSFETswitches. TheINT100  
providesasimple,cost-effectiveinterfacebetweenlow-voltage  
control logic and high-voltage loads. The INT100 is designed  
to be used with rectified 110 V or 220 V supplies. Both high-  
side and low-side switches can be controlled independently  
from ground-referenced 5 V logic inputs.

A floating high-side supply is derived from the low-voltage rail  
by using a simple bootstrap technique.

ORDERING INFORMATION  
Applications for the INT100 include motor drives, electronic  
ballasts, and uninterruptible power supplies. Multiple devices  
can also be used to implement full-bridge and multi-phase  
configurations.
