I was wondering if the 600 mA limit on the motor driver chip is a limit for the total source current of all four motor outputs or for each individual motor output.
If its 600 mA for each motor output,...will the chip get hot when running with 4 motors, outputing 2.4 Amps?

| The 600 milliamp limit is per channel, but for a given motor, two channels are wired in series. So you don't get 1200 milliamps per motor but only 600. This would still yield 1200 milliamps per chip, since there are drivers for two motors. Also, if (...) (29 years ago, 28-Mar-96, to lugnet.robotics.handyboard)

| 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)
