Title: NEED: High Current H-bridge
Post by: madsci1016 on July 08, 2010, 09:21:54 PM

I'm looking for a through-hole h-bridge with current ratings of 5-10 Amps.

Dual channel preferred, but i could just get two.

Current sense also preferred.

Anyone know of any? Google and Digi-key fail me.

dimension engineering have a large selection of dual motor drivers for robot applications from 1 amp to 25 amp.

this might be what your after

I'm building my own motor controller, so i need just the H-bridge.

Was the google animation necessary? That might work, but it's on the low end, I'd really like a 10 Amp capable board.

Sorry for the animation. I haven't had a chance to break that out lately. 5A was the biggest through hole H-Bridge I could find. There were some larger current SMT ones.

Went ahead and bought this:

Now i'll just have a motor controller that's two boards, but saves me from soldering SMD chips like that.
