Hi I want to simulate this IR2103 based half bridge circuit but LT spice seems to be throwing an error: "Analysis: Time step too small; initial timepoint: trouble with node "u1:_gd_template:_input_stage:_lin_th:eek:utp""

I got the spice model for the IR2103 from https://www.infineon.com/cms/en/pro...3s/#!?fileId=5546d4627956d53f01796069eea87040

This is my circuit:

Could someone please help me understand what I may be doing wrong here?

By default the 'A' devices operate at 1V logic level. You need to right-click the A1 and A2 symbols and set a higher logic level, e.g. 5V.
