TEXT 480 -112 Left 2 ;1. Add a "pmos" device to the schematic.\n \n2. Replace the value PMOS with IRF9510\n    on your pmos-transistor in the schematic.\n \n3. Ctrl-right-mouse-click on the transistor\nin your schematic. A dialog window with all\nthe attributes will be shown.\n \n4. Replace the value MP with X.\nThis X tells LTspice that this symbol is for a subciruit.\nOK\n \n5. Add the SPICE-directive into your schematic\n   .include sihf9510.lib\n \n6.  \nI recommend to keep the model file in the same \nfolder as the schematic. This makes a complete\nbackup of a circuit easier than having this file \nin the installation lib\\sub folder.\nHint, this file may contain many models.
