    Matt Kowitt
    I was interested in designing-in the new DRV8824 for a new application requiring (modest) microstepping of a small step motor, but in working through the details of the H-bridge PWM current control, I can't see how to get good performance out of this chip. I'll explain: My main problem comes...

    We'd like to evaluate the DRV8811 stepper controller for a new product using the evaluation module, but they are out of stock at all disctributors and at TI. I called the product support line and they said continue to check online to see when they are available. I'd rather not place an order...

    Kristin Kuipers
    Hello everyone, I have problems with the DRV8432. I am driving the device with a non-simultaneous, complementary PWM signal, 12 V supply and a 1mH load. I have voltage dips on one side of the coil. It's always the side whose the high side is turned on longer and the problem gets worse when...

    Hi I'm new to the DRV8811 and have a first proto board up and running driving two small-ish hybrid steppers connected in series bipolar fashion. They are 8-wire types with 1amp 5V phase windings (each of the 4). So in series they are "10V 1amp". They step OK after a bit of fooling...

  • Forum Post: Overcurrent protection in DRV8811

    Alexander Vasiljev
    How overcurrent protection is designed in drv8811? It seems that drv8811 in our circuit stops due to overcurrent protection. We need to know how it is designed to find a reason.

    Hi, I have designed a dc motor speed control using drv8801IC, in which phase pin of drv8801 is used as direction input and enable pin as pwm input pin. Every thing is workig fine. The schematic file is as below. I have connected 1ohm resistor to sense pin which in turn allows only maximum of 500mA current...

    Steve, What are the issues with driving the DRV8412 below 10KHz? We are trying to use this device to drive stepper motors at frequencies <1KHz. Do you have a device to offer at drive frequencies that low? Best Regards, Jim

  • Forum Post: Re: DRV8825 Overcurrent Protection Issues

    Jordan Meyer
    Jose, Thanks for your help with our design. As it turns out, the over current and over temp was tripping because I had the decay pin set to fast decay. Once that was changed to mixed, our design could match that of the evaluation board. To anyone with concerns, see Jose's previous comment and...

    I have been evaluating the DRV8825 for a single axis stepper motor drive. We purchased a DRV8825EVM board and I was able to develop most of my code on that platform. I also bench marked the current in the motor windings using a current probe on an oscilloscope while driving a 6 port Valco Valve with...
