| | | I just realized that getting 1200 milliamps running two motors bi-directionally is equivalent to running four motors uni-directionally at 2400 from a total power dissipation standpoint. I.e., there are still 600 milliamps running through each (...) (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

| | | | (...) 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)

| | | | (...) 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 (...)
