Default Re: Power MOSFETs

I'd be tempted to use a cheap microcontroller to generate a PWM signal by simple bit-banging, and a pair of TDA2030-alikes with no feedback to drive the gates of the MOSFETs, for the current sourcing and sinking ability. For 3-phase, make the table with a multiple of 3 entries and start reading 1/3 and 2/3 of the way through to drive the other phases. Software timing should be accurate enough, you know how many cycles the lookups and writes will take, and the only decisions will be in the idle loop.
