Hey everyone, Here's my dilemma: I've got a voltage that varies (say from 0-5v) and I'd like to have this voltage control a DC motor via Pulse-Width Modulation. I've got the actual high-current motor driver (MOSFETs) done, I just need some pulses for it. It seems like there should be a chip that does all this, has an adjustable PWM frequency, and provides a way to drive the motor both forward and reverse (2 seperate outputs, one for forward, one for reverse) Any ideas? Surely this must have been done thousands of times. All help appreciated. BTW, this is for an Electronic Speed Control (ESC) for an RC car. Thanks, Tod tod@sandman.caltech.edu tkurt@vlsi.caltech.edu
