    Hi Alon, thank you for the update. Let me know if I can assist further after the testing. Best Regards, -Joshua

  • DRV8305: About VREG

    Part Number: DRV8305 Hi team, Is there any provision for the rise time of VREG? I have created several boards with the same circuit, but the rise time of VREG is different for each device. Best, Ryu.

  • DRV8305-Q1EVM: nFault issue

    Part Number: DRV8305-Q1EVM Other Parts Discussed in Thread: DRV8305 Hi Team, Using F28069M+drv8305 for m otor control and the control algorithm being used is motor ware's InstaSPIN-FOC. At 900 control frequency per second, if a fixed control current…

  • DRV8305: Unclear Gate Timing

    TI Thinks Resolved
    Part Number: DRV8305 Hi together, I have two follow up questions to my original question regarding the timing of the DRV8305 Gates. It was: Could the parameters t_pd_if-O and t_pd_ir-O be the time between INH_x rising/falling and the low side gate GLS_x…

  • DRV8305: Radiated Emissions releated to DRV8305 Internal Clock

    Resolved
    Part Number: DRV8305 I use two DRV8305NPHPRs on my custom pcb for two BLDC motors. I tested radiated emissions about the pcb. Then I found peak emissions around 120MHz. The source of peak emissions are most likely caused by DRV8305 internal clock. Because…

  • RE: DRV8305: DRV8305 Current Sense Amplifier

    Adam S said: So should I add additional OpAmp buffer between CSA output and ADC input? Not necessary since there are three embedded PGA on DRV8305 which can be connected to the ADC pin of C200. You may just just need to add a RC filter between the output…
