IR-HCdrv.zip contains a library of hierarchical behavioral models 
for thirteen high current half-bridge driver ICs from International 
Rectifier.  These hierarchical model files have been developed in-
dependently by me, analogspiceman@yahoo.com, without the knowledge 
or approval of International Rectifier.  They are specifically for 
use with LTspice, a complete and fully functional SPICE program 
that is available free of charge from Linear Technology Corporation.  
They are supplied "as is" and, although believed to accurately model 
typical driver IC switching behavior, are not guaranteed in anyway.  
Comments and suggestions for improvements are more than welcome. 

Those not familiar with LTspice's hierarchical schematic capability 
should refer to the topic in LTspice's Help file.  Each IR driver 
model used within your top level schematic must have a copy of its 
individual symbol and schematic (i.e. one .asy file and one .asc 
file per driver) co-located in the same folder with your schematic. 

The following instructions will help "first timers" to place an IR 
driver library hierarchical symbol onto their LTspice schematic:

1) From within the schematic editor window, open the "Place 
   Component Symbol" dialog box as usual. 

2) At the very top of the box click on the down arrow to get 
   the drop-down selection pick list for a new "Top Directory". 

3) Choose the folder where your working schematic currently is 
   located and the IR driver symbol should now appear in the 
   symbol selection area. 

4) Select it and place it on your schematic as usual. 

If desired, you may open the sub schematic (the IR driver) by right 
clicking on it from within the top level schematic (your switching 
power converter design).  In this way you gain access to internal 
driver nodes during a simulation and thus can plot node waveforms 
with a simple point-and-click (be sure you've enabled save sub 
circuit node voltages/currents from within the "Save Defaults" 
tab of the Control Panel). 

Good luck! -- analogspiceman
