Marketing proposal for customer feedback. No commitment taken to produce Proposal: Limited Engineering samples available Preview: Right now looking at it your Arduino ground isn’t tied. From the fine datasheet: You are at a point where we aren’t going to be able to debug over the interweb. General terms and conditions. Log in or sign up in seconds. The OP has attached the 5v to the VREF dataxheet which are used to figure out the signal voltages so it knows what’s high and low.

Distributor Name Region Stock Min. Does anybody know why? Buy Direct Add to cart. The device also includes two independent constant off time PWM current controllers that perform the chopping regulation.

Don’t forget that the motor inrush is much higher than stall current. L, L, L dual full bridge drivers. I can’t tell from your diagram if you did.

Submit a new text post. I got an IC for driving two DC motors an STM L in a Datashet 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.


You need the common ground. What motors are you using this with as well as how are you getting that 48V DC? Not Recommended for New Design.


Do you have access to a scope? Free Sample Add to cart. Product is in design feasibility stage. Support Home Complete list and gateway to support services and resource pools. In case it wasn’t clear from the schematic, the supply voltage for the IC is 48 VDC, so that perfectly within range. 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. 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.

No commitment taken to design or produce NRND: Strictly speaking, I’m not running a motor with it but actually an electromagnet, which acts as the stator for a linear motor.

Product is in volume production. However, there still is no voltage between any of the output pins. Did you also connect some supply power to it.

L – DMOS dual full bridge driver with PWM current controller – STMicroelectronics

Need help with motor driver IC self. Product is in volume production 3. Cloud Components and Modules. Product is under characterization. You aren’t going to be powering that chip from the 5V output of the Arduino. If you can do SMD work you can get a lot of these chips very cheap. IoT for Smart Things. Media Subscription Media Contacts. 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.

Key Features Operating supply voltage from 8 to 52 V 5. Reducing torque variation in half step drive. Now you are really doing to have to do your own debugging by going through each input and checking the expected values. Become a Redditor and subscribe to one of thousands of communities.
