  • RE: DRV8303: DTC not working properly on DRV8303

    Good afternoon James, I apologize for my mistake. The signals on my breakout board were actually connected to the gate drive signals from the microcontroller (used as inputs to the DRV8303). This explains the lacking PWM deadband and also voltage levels…

  • RE: DRV8303: SPI communication issue

    Mayank, Your schematic didn't come through, could you please repost it? Regards, -Adam

  • DRV8303: 14 s battery pack

    TI Thinks Resolved
    Part Number: DRV8303 Other Parts Discussed in Thread: DRV8353 Hi, I know the DRV8303 can work up to 60V of power supply and an absolute maximum of 65V but for a 14s battery pack system (58.8V max) the limit is too close to the maximum voltage of the battery…

  • RE: Compiler/DRV8303: drv8303

    Hi Rick! I made SPI-communication with DRV8303 and increased OC-protection value. After that - everything start work good))) Thank you! If you will plan visit Ukraine - inform me! I'll buy to you bottle of good whisky))) Pavel.

  • RE: DRV8303: DRV8303 GVDD drops down to 2.3V

    Hello Rick I am getting a little desperate with this, I have lowered the gate current, increased the gate resistors, added diodes and caps on the low side source and power GND and I still cant get close to 48V without the GVDD dropping. I have replaced…

  • DRV8303: What is Device ID?

    Part Number: DRV8303 What is the Device ID that can be read by Status Register 2? Also, there are cases where it can be read as 0 and cases where it can be read as 1, why?

  • DRV8303: gate drive output burn

    Part Number: DRV8303 Hello I've doubled the motor phase current of my FOC brushless motor controler, now after some time the drv8303 gate drive output burn, how is it possible? the 6 mosfet are BSC076N06NS3GATMA1, there is a 10Ohm resistor between…

  • DRV8303: About the deviation of the motor speed

    TI Thinks Resolved
    Part Number: DRV8303 The average rotation speed of the motor converges at 102-103% of CLKIN. I understand that the hall signal from the motor is not uniform and has a variation of 10 to 20%. Is it expected that the average speed will deviate by 2-3% as…

  • DRV8303: min max values for bootstrap resistor

    Resolved
    Part Number: DRV8303 Hi MDBU Team, We need the information about the resistor values of the bootstrap charge path of the DRV8303 as it is not written down in the datasheet. Min. Value && Max. value over temperature range Many Thanks Best…

  • RE: CCS/DRV8303: DRV8303

    Hi Carlos, Thanks for the gain confirmation. I would suggest sniffing the SPI transactions to make sure the gain is fixed. Some scopes have this ability.
