  • RE: DRV8350H-EVM: Software sensorless tuning issue

    julien leconte said: We set the current in the graphical interface or in the software by forcing the value of 2606. This confirms my suspicion that the GUI has an error of using 'A' -- current in Ampere -- as the unit for this parameter, which is really…

  • DRV8350H-EVM: Efficient and accurate BLDC motor control

    TI Thinks Resolved
    Part Number: DRV8350H-EVM We are trying to control a small medical 3-Phase BLDC motor to get a wide range of RPMs. For the testing, we are using the DRV8350H EVM. We have adjusted firmware to use 6-PWM mode. Our current firmware is using the Hall Sensors…

    Part Number: DRV8350H-EVM hi, i am using this driver ic for 100% duty cycle pwm signals input.i have connected INL signals to ground and connected INH signals to GPIO pin of controller. i am trying to make on/off INH signals but i could not see same on…

  • DRV8350H-EVM: I cannot drive the engine properly with the DRV8350H.

    TI Thinks Resolved
    Part Number: DRV8350H-EVM Hi, I have two different motor driver. One is DRV8320S and the other is DRV8350H. While I could control the engine very well with the DRV8320S, I couldn't do it with the DRV8350H. I also make the necessary resistance settings…
