  • DRV8304: Phase action under no load

    Resolved
    Part Number: DRV8304 Hi, Is there some feature in this DRV that disables it when it senses no load across the phases? If not, does the DRV do anything at all when motor phases are not connected but everything else is connected and is working correctly…

  • DRV8304: Using CPH to drive a MOSFET

    Resolved
    Part Number: DRV8304 Hello, I know the DRV8304S comes with a charge pump to drive high side MOSFETs and that the VCP pin gives us the charge pump output. I would like to use that voltage (~ VM+13.5) to drive a different MOSFET (not one of the half bridge…

  • DRV8304: Problem with phase waveform in 1x PWM mode

    Resolved
    Part Number: DRV8304 Hi, I am running my DRV8304S on 1x PWM mode. The phase waveform is a perfect trapezoid when DIR=0 (INHC input). When DIR=1, the waveform looks like this: As you can see, there are some stray PWM signals in between the trapezoids…

  • DRV8304: Question about AutoCal for automatic offset cancellation

    TI Thinks Resolved
    Part Number: DRV8304 Hi team, I want to know how AUTOCAL works? After AUtoCAL started, what kind of operation did the op amp perform? (In addition to connecting the input to ground), how do we perform the calibration? (Adjusted the internal resistance…
