  • DRV8311: If inrush current will impact the reliability

    Resolved
    Part Number: DRV8311 Tool/software: Hi team, Below waveform is measured at motor start-up period. It is the phase A current. You can see the peak is about 2.75V which represent 7.5A. At the beginning, the OCP threshold was set to 5A. They found the…

  • DRV8311: The OUTx issue and schematic review

    TI Thinks Resolved
    Part Number: DRV8311 Tool/software: Hi, We use the DRV8311 for the BLDC which used for the d rone gimbal, please refer to below screenshot, we want to know if we don't connect the SOA/SOB/SOC to MCU ADC because our MCU has no eought ADC resource…

  • 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…

  • DRV8311: DRV8311S part Status and use of DRV8311H Instead

    TI Thinks Resolved
    Part Number: DRV8311 Hi, Hi, We are using DRV83053PHPR in our products which require high current to drive the BLDC motor preciously. For our miniature, space constraint products we are exploring DRV with integrated MOSFET and sense resistors. DRV8311…

  • 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…
