full bridge motor driver using PWM

You mean

im sorry the company name was what i had on the top of my head. Thanks very much for correcting me

Thx. My application requires an controller that can drive a bit more. Do you know of any that drives up to 30A?

This doesnt answer ure qn directly. But i have built my own HBridge using IRL3803 and IRF4905 Mosfets they can take 55A.

I switch them at 100Khz. But my design isnt good as u need to drive the gates using enough gate drive as the gate capacitance of mosfets are large. But to serve the purpose i use ttl logic to drive the gates and it does the job :-)

You could look at the ST L6384

This turns TTL control signals into Upper and Lower drive signals (including deadtime) for a single arm of an inverter. You can directly drive fairly substantial MOSFET's from this.

I've run largish FET's with 24Vdc input up to 100kHz with these.

If you need small quantity's, you could look into ready made amplifiers as made by amc

For motors upto 3Amps i always used a LMD18200. But lately i start looking into designing a similar bridge with discrete components. Mainly because sometimes i don't have the pcb space for a TO220 package.

Anyone some more suggestions on making a good 3A. H-Bridge ? (Driver IC + Mosfets)
