Chris, thanks for the feedback. Are you familiar with a larger h-bridge or external driver that does PWM locked antiphase? There might be many, but I haven't been able to identify a part. If you know of any that can do 6A+ and locked antiphase please let me know the part number. I understand what you are saying about the gating requirements, but do you think if I fed the outputs from the LMD18201 into the inputs of a TLE 5206-2, for example, I could drive the coil that way, or would it still require extra logic? I'd prefer not to have to use both parts, but it is worth considering if nothing else is available. Thanks again.
