  • RE: DRV8306: Set the right R_ISEN value and power rating

    Resolved
    Hello Tomer, Your calculations care correct, at 30 A the R29 shunt resistor on the DRV8306EVM would fail. The DRV8306EVM is limited to support a maximum of 16A due to the max current rating of the J5 connector ( 691101710002 ) used for VM. This limits the…

  • RE: DRV8306: Set the right R_ISEN value

    Resolved
    Hello Tomer, Tomer Bruchiel said: I would like to understand how to calculate R_ISEN? Your calculations are correct if you are attempting to determine a Rsense value for a Pulse-by-Pulse limit of 40A. On the DRV8306EVM the Pulse-by-Pulse current limit…

  • DRV8306: Is there a formula for calculating RSEN for a given current?

    TI Thinks Resolved
    Part Number: DRV8306 We have built an integrated driver circuit based on the DRV8306EVM and need the formula to calculate the R29 value to control our output current. Can anyone please share this formula?...it does not appear in TI documentation and is…

  • RE: DRV8353RS-EVM: BLDC MOTOR DRIVE

    Resolved
    Hi Amol, Please evaluate the DRV8306EVM . It is a PWM controlled gate driver with sensored trapezoidal control and Hall sensor feedback. You could also look at using 1x PWM mode in the following devices/EVMs: DRV832x BOOSTXL-DRV8320S BOOSTXL-DRV8320H BOOSTXL…
