Thread: 3A H-Bridges in Bangalore

  1. #1

    Default 3A H-Bridges in Bangalore

    I used to use L298 to drive steppers; I just realised that it wastes half the power it consumes by pushing half the current through the current sense pins. I found a bunch of alternatives - notable LMDxxxxx chips. But as is generally the case, these might not be available here in Bangalore.

    The Ideal H-Bridge driver for me, would be a quad half H-Bridge driver able to handle 3A per H-Bridge, and possibly with low power dissipation current sense circuit - LMD18200 comes close - and most important of all, it must be available at SP Road. Sort of a L293 capable of handling 3A, but not a L298.

    What has been your experience on this ?

    Yeah, well this was the first thought that struck my mind. I don't find etching PCB's very neat - must be my printer; and making four of these out of veroboard and lots of solder is surely going to be a very big pain.
    Any other ideas ?

    For the H-Bridge Ic's try Om Electronics or Vishal Electronics in SP Road. If you don't find it in these two places, you will not find it anywhere else.

    If you want to get PCBs fabricated at cheap prices visit www.probots.co.in/index.php?main_page=page&id=4

    Its not much of pain also.It'll take you about 1/2 hour in one circuit board.Try it.You will also definitely improve your soldering.
