  • DRV8304: DRV8304H - Mode pin voltage on power up

    TI Thinks Resolved
    Part Number: DRV8304 Hi, We are using the DRV8304H in 1xPWM mode and on a new spin of the board the DRV8304H appears to be coming up in 6xPWM modDRVe instead. The only output phase showing any PWM signal is GHA corresponding to INHA. Previous versions…

  • DRV8304: Backwards EMF + Damaging the battery

    Resolved
    Part Number: DRV8304 Hi. We have a product for an electric wheelchair. We do not necessarily want to do regenerative breaking, but when going downhill, the chair will make the motor turn... so if we go fast enough, the motor will generate a voltage higher…

  • DRV8304: Can drv8304 drive my mosfets?

    Resolved
    Part Number: DRV8304 Hi, I calculate the IDRIVEP and IDRIVEP like the equation in datasheet: Idrivep> Qgd/tr and Idriven>Qgd/tf, my mosfet has tr = 23 ns to 50 ns and Qgd 12,3 nC so IDRIVEP is ca. 0,53mA to 0,246 mA the DRV8304 has a minimum of…
