I have a problem with one of my ICs. I think that is what is the problem:
When on the picture (taken straight from the IC's datasheet) it says connect the lead to the ground I usually connected the negative terminal to that spot, am I wrong?
What I have is an H-bridge: L398N. I am building a robot where I need a forward and reverse for the driving dc motor. With the picture from the L398 datasheet (connecting the 'ground' pin to the negative) I get the voltage output from one of the 'out' pins (as measured against the negative terminal) but the other 'out' seams not to be connected to the negative to make the motor turn. I tried using an independent transistor instead of the other 'out' but it does not work. (it does work with a bulb :roll: :!: :evil: )
I redid the circuit about 30 times now, I have five of those H bridges this thing still does not work. My woltage suply is 7.2 volts (it turns the motor if pluged straight in). For the logic voltage is 5 v from a voltage regulator.
So if all my mumble is very confusing, my question is how do I connect the ground pin? However do help me if you know about those H-stupid-bridges
