2. Sign/Magnitude ControlFor this mode two ports with PWM capability are necessary. Motor turns clockwise(current flows from OUT1 to OUT2; means: OUT1 is switched HIGH continuously andOUT2 is PWM controlled.
This TLE5206-2G IC seems good. I just wanted to check and make sure I understand its operation before I destroy something. On page 15 of the datasheet it says:Then it shows a diagram. Am I correct in saying the following knowing that my power supply is 12v?The difference of IN1 and IN2 is proportional to that of OUT1 and OUT2. For instance, if IN1 is set to 5v and IN2 is set to a PWM signal of 1v, this is a difference of 4v out of the 5v. Proportionally to 12v, OUT1 and OUT2 now have a difference of 4/5 * 12 or 9.6v or 80% power.Is this correct?
OUT1 will output 0v and OUT2 will output an average of 6v (half of 12v).
how much voltage drop does it have (that is, of course, a big thing to know considering my power source and motor have the same voltage ratings), and how do I find this out using the data sheet?
In addition, how many volts below the nominal voltage of the motors is acceptable?
