The VNH5019A-E itself cost $9.20 qty 1, from DigikeyLooks good. Heat sink will be neededI'll buy one full board from polulu for testing.
While the overvoltage protection typically kicks in at 27 V, it can trigger at voltages as low as 24 V, so we do not recommend using this motor driver with 24 V batteries, which significantly exceed 24 V when fully charged.
For my amps requirement, i could use 2 VNH5019A to get 24 A (60 A peak) to a single motor connected to both channels but i still have the 24 volts overvoltage protection issue.Documentation also says that it can survive input voltages up to 41 V.
The below might be worth looking at.http://www.monsterscooterparts.com/otco.html
Hi,Everything going well about this project. I have one question... For test purpose, is there a problem running my 24 Volts DC 450 watts motors with only one 12 Volts battery ?
The maximum current on my motors are 4A, but that's only around stall, they typically run around 1-2A, so I have have a TIP120 and an L298 in series for each motor.
No, i do not have lots of knowledge and experience but i'm ok with programming Arduino. I have to get 50+ units, would it be smart to go DIY and be guided ?
