HI
Just wondering what kind of success anyone has had with
piggy-backing the L293's. My HB came with the TI h-bridge chips and I
wanted to know if I could use the same technique. I figure if two chips
can be run in parallel, giving up to 2A for each motor, I should be OK with
the motors I have.
Also, can the traces on the board itself handle that kinda current.
I don't anticipate running all four motors at 2A, but if something goes
wrong will I melt the board.
Thanks
Matt

| (...) The TI chips should work fine. You might not get a full 2A, but at least a 50% improvement. (...) The traces can handle it, but the PolySwitch fuse should limit total current to about 4 to 5 A. You might need to remove the fuse and live (...)

| Hello there. I've piggybacked three chips, for a total of 2.6A (2 1A chips and 1 0.6A chip, piggybacked with heat sink compound slathered between all the chips and between the top chip and the heat sink I've put on it). I haven't had any problems (...) (28 years ago, 10-Jul-96, to lugnet.robotics.handyboard)
