        Re: 600 mA Limit —MAR ERICSON
   (...) OK. I just wanted to make sure I'm understanding the material. So, my guess is that in order to drive the 4 motors off one chip, you would have to ground the other lead of each motor? So, does that mean that there is 2.4 A source from the chip (...) (29 years ago, 29-Mar-96, to lugnet.robotics.handyboard)
   
        Re: 600 mA Limit —Fred G. Martin
   (...) from the L293D ground? yes, this would be correct. Well, there would be 2.4 amps running through the chip's power source, into the motors, and into ground. ...totaling 4.8 A runniing throught the entire chip fro m a power dissipation (...)
