Limit current of L Bridge Driver. Hello, I’m currently building my first stepper motor driver, a bipolar stepper, 4. Basically it works fine, but the current is much too high.

At 12V my 2. At 7V the current at stand datasheef is more than 1. So I suppose I have to limit the current, but I am not sure how. The datasheet mentions an integrated PWM current control but I can’t find any further information on how to use it.

It explains how to the overcurrent protection can be used to roughly regulate the load current what I have tried, it works but the motor then runs choppy and I feel sorry for it. Another thing I don’t understand is why the driver still works if I remove the charge pump?

Thanks for the suggestion, I already did try that, it works to limit the current but the motor runs awfully noisy and choppy and loses steps. I suppose that’s because in effect datasjeet is like very slow PWM. I doesn’t seem to be possible to improve that by reducing the shut down time of the overcurrent protection below what you get with kOhm and 5.

I’ll try to PWM the enable voltage as it seems to be possible with the L I really wonder how one is supposed to regulate the current with the L dataaheet it doesn’t have a reference voltage pin like most other drivers have. Maybe I bought the wrong driver, it doesn’t seem to go well with the stepper motor I have. I can and will only repeat once more: Just to follow up Yes, I am aware of that, and Daasheet chose the resistors to get a threshold of 1A.

It runs perfectly fine without overcurrent protection.

Overcurrent detection is meant to detect a fault condition, not to control normal operations, or am Dtasheet wrong? It feels like using exceptions to control normal program flow. The L simply does not offer current control, while the L does.

But it is way too expensive I think. I did not do any PWM while testing overcurrent protection. I’ve built the circuit on a breadboard exactly following the diagram “Figure A picture of the circuit is attached.
