Hello, I am a member of the UCF Robotics Society (IEEE Student
chapter) and we do lots of work on robots designed with DC brush
motors. To put it bluntly, we need an H bridge controller able to
handle more power. Ideally a 24V at 8 Amp with spikes of
20-25 Amps would suit us. We have been using Unitrode
L298's, which max out at about 2 Amps, if I remember correctly.
I have looked at Motorola's MP3002 Mosfet H bridge, coupled with
another controller chip, (100V,8Amp cont, 25 spike), but have
been having trouble getting them. Have any of you been using
chips with similar specs, or know of them?

Or, if you have a good schematic for a TTL controllable 
transistor H-Bridge, I would appreciate it. (I am just a Computer
Science major)

Email or Post, thanks in advance.
