I am in the process of designing a motor controller circuit. A PIC microcontroller will create/control a PWM signal which will be "inputted" to an H-bridge controller which will drive a brushed DC motor either forward or reverse.
I am looking for a simple H-bridge model with PWM inputs, dual motor outputs (bidirectional), etc. defined so that I can design my circuit. I would like to be able to somewhat simulate PWM control Any suggestions?

Hello All,
Wondering if anyone has a PWM input bidirectional h-bridge driver model for LTspice?
amhtech,
I don't know what you mean by "PWM input bidirectional h-bridge driver model.", but most drivers sink and source current. The power switches normally have reverse diodes, so, in effct they are bidirectional. If you clarify your question, you may get a better answer.
