  • DRV8231A: Why the motor current of DRV8231A is different from DRV8870

    TI Thinks Resolved
    Part Number: DRV8231A Other Parts Discussed in Thread: DRV8870 Hi team, We want to replace DRV8870 with DRV8231A. We were testing DRV8231A and found that motor current controlled by DRV8231A was smaller than that controlled by DRV8870 when the motor speed…

    Renan, Any updates? Regards. Pablo Armet

  • RE: DRV8231A: Why current was tested when no motor was connect to the OUT1 and OUT2

    Hi team, I am back! I tested DRV8231A without load on DRV8251AEVM and found a strange phenomenon which need you to help analyze. As the waveform below, there is a voltage(V1,about 20mV) after the IN2 signal‘s rise edge(The time between the rising edge…

  • DRV8231A: VREF Current

    TI Thinks Resolved
    Part Number: DRV8231A Hi Team, I have a question about DRV8231A. In the Vref input, is what is the current into this input (what load does it present)? The data sheet mentions that the voltage at the IPROPI pin is clamped in the event that this voltage…

  • DRV8231A: Max VREF voltage

    Resolved
    Part Number: DRV8231A Hi, I'm looking for a help on understanding the max VREF voltage for the DRV8231A part, as the datasheet seems to give slightly contradicting data on this. Ideally, I wanted to get the maximum usable range for IPROPI, and my external…

  • RE: Which motor driver to choose?

    Resolved
    Hi Egil, The DRV8231A will be the best solution. This driver is a single BDC motor driver with integrated H-bridge and current sensing for limiting the current during motor startup. In your case, you'll need two motor drivers, one for each motor. The…

  • RE: Required IC or driver to drive https://www.omega.com/en-us/industrial-heaters/surface-heaters/flexible-heaters/khra-khlva-kha-series/p/KHLVA-101-5-P part

    Pooja, Based on your requirements, the DRV8231A is a good option. It does come with current regulation and overcurrent protection. pooja ak said: Understood! please suggest an additional PID control . I can't really recommend a PID loop as that is not my…
