Sorry, I didn't understand the question clearly, because my english is not good enough. Then as dstich say many thing around going forward and inverse, I didn't read the first line clearly. He need to driver a carstarter, but I think he is a starter on robot
. so sorry.
I don't know muchie bout car, but the honda motorbike starter. I can buy starter with ease and of course, it work with 12VDC batteries. In my country, motorbike is the main means of transportation.
However, starter creat a great tours upto dozen thousands rpm. And I don't think it's good for a robot.
Besides, the max current on the starter can get is about 4A only, because I used the small 4A - 12VDC batteries to drive it. The normal motor is only about 180mA, 250mA or higher such as 500mA.
I don't know what ante means as telling meeh to use 100 L298, were you teasing meeh? Well, sorry because my English is not good, and I didn't understand ur joke.
As I know about motorbike starter, it creat a great rpm and via the gear, it generate a strong torque to start the motorbike.
You can imagine that, a normal fan is only 40W which use 220VAC, that is the current is only about 260mA.
And I think it's the same to car starter in principals. And for sure, you can build 7A motor driver with D718.
