  • RE: DRV8306: Strange gate voltage and motor cannot start

    Hi Hai, Yes the order is a factor, so ideally if the hall sensors are matched correctly (A phase of motor -> A phase of driver, Hall sensor A of the motor -> HPA and similarly for B and C phase) the motor will spin up fine. Sometimes, the motor phases…

  • DRV8306: Monitoring VGS threshold voltage for Gate Driver Fault (GDF)

    Other Parts Discussed in Thread: DRV8306 Tool/software: Hi team, The FAQ in E2E said that “Generally, the internal monitoring threshold voltage is around 2V” about VGS ON/OFF thresh for GDF detection. The thresh of DRV8306 is also around…

  • DRV8306: New design : Understanding between VDS limit and current limit with ISEN/RSENSE

    Resolved
    Part Number: DRV8306 Tool/software: Hi community Can you explain difference between VDS overcurrent limit and current limit with ISEN/RSENSE ? As I understand: - VDS overcurrent limit is to protect the MOSFETs, so VDS_OCP voltage must be set according…

  • 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…
