Need help with motor driver IC self. I got an IC for driving two DC motors an STM L in a DIP24 package, datasheet here and I wired it up as illustrated here but when I output the correct logic as described in the datasheet, there appears to be no voltage between any of the output pins. Updated the circuit to the one recommended on page 16 of the datasheet, wired it up like this. However, there still is no voltage between any of the output pins. Can somebody tell me what I am doing wrong?

While it is definately the right way to go, it still didn’t help. I also should have mentioned earlier that although there is no real voltage to speak of between the output pins to speak of, what little there is 0.

Current layout and pics can be found here. Please refer to page 16 of the datasheet. You are missing quite a bit of components to get this chip up and running. This device needs some external caps and resistors to get the charge pump to operate that drives the upper fets of the integrated h-bridge. Did you also connect some supply power to it. I can’t tell from your diagram if you did.

You aren’t going to be powering that chip from the 5V output of the Arduino. Also, if you are really going to be running the full current capacity through this chip then the bread board is going to get a little angry. That’s the voltage for the H bridge itself, as in the supply for the H bridge part itself and not the logic circuitry voltage. The OP has attached the 5v to the VREF pins which are used to figure out the signal voltages so it knows what’s high and low.

Arduino has enough current for that coming off the 5v pin.

It’s wasn’t very obvious from his fritzing diagram that the little black barrel jack is where he is bringing in the bridge supply. I still stand by the fact that he really needs to look at the REF circuit that ST provides on page In case it wasn’t clear from the schematic, the supply voltage for the IC is 48 VDC, so that perfectly within range. Are you using some big motors? Don’t forget that the motor inrush is much higher than stall current. You need a common ground between the Arduino and motor bridge and the battery.

Right now looking at it your Arduino ground isn’t tied. You need the common ground. What motors are you using this with as well as how are you getting that 48V DC?

Forget linear voltage regulators because lots of wasted energy. Strictly speaking, I’m not running a motor with it but actually an electromagnet, which acts as the stator for a linear motor. Digikey seems to be the only one who has the DIP version in stock: If you just need something to power small motors say toy DC motors look at this: If you can do SMD work you can get a lot of these chips very cheap.

Here’s the product page. Do you have access to a scope?

It would be helpful in this situation. Now you are really doing to have to do your own debugging by going through each input and checking the expected values. You might want to consider using the evaluation board if you can’t debug the layout on your own.

Does anybody know why? I really want to get this to work Dataasheet to add to the discussion? From the fine datasheet: I’ll try that ASAP!
