  • DRV8306: Isolation

    Resolved
    Part Number: DRV8306 Tool/software: Can you use the gate outputs to drive an isolated gate drive for a 270V motor? I would set VM at 6-7V. Would it be necessary to still use the charge pump to avoid getting a fault? If so and I use VM at 7V what would…

  • DRV8306: Set the right R_ISEN value

    Resolved
    Part Number: DRV8306 Other Parts Discussed in Thread: CSD18514Q5A , CSD88584Q5DC Hi, I would like to understand how to calculate R_ISEN? In the EVM it is set to 0.007Ohm but I do not know the pulse by pulse current limit based on it. From what I can understand…

  • DRV8306: Set the right R_ISEN value and power rating

    Resolved
    Part Number: DRV8306 Hi, In regard to the previous question, it was explain how to select the R_ISEN value (Based on the 0.25 Vlimit). From that I derive that the power rating of the resistor should be I_max^2*R_ISEN. If I look at the selected R_ISEN…
