  • DRV8311: DRV with integrated CSA and safe 24V operation

    TI Thinks Resolved
    Part Number: DRV8311 Other Parts Discussed in Thread: DRV8316C Tool/software: Is there a part similar to DRV8311 feature-wise, but that can run safely on 24V? most parts in that power category has a 20V limit (abs max 24V..), problem with 20V is that…

  • DRV8311: Different test waveforms

    Part Number: DRV8311 Hi, The customer uses f28388 to control the DRV8311p. The f28388 outputs a 20khz synchronization signal to the pwm_sync pin of the drv8311. The PWMG_CTRL register is configured as pwmg_ctrl_data=（0x1《10）｜（0x0 《8）｜（0x2 《5）. After configuring…

  • RE: DRV8311: Questions about DEV_STS1 and PWM

    Hi Chun, I apologize for the long delay. If this is still an open question I would like to ask if this 0x81 fault status permanently goes away after being manually cleared? It may have been possible that the fault status was triggered during device power…

  • DRV8311: Some questions about PWM

    Resolved
    Part Number: DRV8311 Hi I have a few questions about the PWM of DRV8311P Q1. How does DRV8311P generate center aligned complementary PWM? Q2. How does the PWM of DRV8311P align with the time base of MCU's TIM Q3. How to obtain the waveform of the…

  • DRV8311: Do I need to set dead time if DRV8311 has fully protected ?

    Resolved
    Part Number: DRV8311 As DRV8311 has full protected Do I still need to set dead time insertion settings (or leave it as 00h ) ?

  • DRV8311: PWM Generation Mode

    Part Number: DRV8311 Hi Team, Customer has the following two questions and needs your help. He used DRV8311P, when using PWM generation mode: Q1: The PWM cycle, duty cycle, dead time and other related parameters are configured through the tSPI interface…

  • DRV8311: Are there chances DRV8311P refelect VM voltage back to MCU to burn up MCU

    Part Number: DRV8311 Other Parts Discussed in Thread: TMS570LC4357 I deigned a Motor Driver circuit, which uses TMS570LC4357 MCU to drive DRV8311P via tSPI. When rotate the motor with SVPWM with constant rotation rate, it works fine. when it keep motor…

  • RE: DRV8311: In pwm output mode, the waveform output by HS_ON position is different from the manual

    Hi Annie, I apologize for the delay. I would like to confirm that the register values are matching up to the example condition, so can you provide these settings again in Hexadecimal: Annie Liu said: Pwmg_ctrl_data = (0x1<<10) | (0x0 << 8) | (0x2 << 5…
