DRV8306: Automotive Grade Part

Part Number: DRV8306
Other Parts Discussed in Thread: DRV8340-Q1, MCT8316Z, DRV10983-Q1, DRV8305, DRV8305-Q1, DRV8343-Q1

Do you have an automotive version of DRV8306? If not do you have a part that has a similar function as DRV8306 but is automotive qualified?

    Hello Tejas,

    Unfortunately we do not have a driver quite like the DRV8306 in automotive. The DRV8340-Q1 is close, because it does integrate sensored trapezoidal control (1x PWM), but it does not integrate the current limiting feature, only overcurrent protection.

    If you are driving a low power motor, a solution like DRV10983-Q1 may be interesting to look at. MCT8316Z is another similar part with the MOSFETs integrated and we do plan to release an automotive variant of MCT8316Z in the future.

    Thanks,

    Matt

    Can we connect Hall A, B, C sensor output to STATE0, STATE1, STATE2 respectively instead of MCU?
    We would like to run DRV8305 independent of MCU. Please let us know the feasibility.

    Hello,

    DRV8343-Q1 or DRV8340-Q1 are better to do this than DRV8305-Q1.

    DRV8305-Q1 lacks a direction pin in 1x PWM mode, meaning the motor can only spin in one direction. DRV8343-Q1 and DRV8340-Q1 have a direction pin in 1x PWM mode.

    Thanks,

    Matt
