  • DRV8302: Internal Amplifier Characteristics

    Resolved
    Part Number: DRV8302 Hi team, Do we have any characterization data or specs for the integrated current sensing amplifiers of the DRV8302? I know there are some specs for offset and gain, but what about things like gain bandwidth product, linearity, zero…

  • DRV8302: What is the maximum high and low level transition frequency of the gate of this IC?

    TI Thinks Resolved
    Part Number: DRV8302 Other Parts Discussed in Thread: DRV8301 , Hi team, The customer is wondering what is the maximum frequency at which the gate high and low level transitions of the DRV8301/8302 outputs can be made? Is it based on f_gate 200kHz(MAX)…

  • DRV8302: cannot startup properly

    TI Thinks Resolved
    Part Number: DRV8302 Hi team, Here's an issue from the customer may need your help: After power-up, the chip is not able to startup properly, the measured pin DVDD, AVDD,GVDD are all 0V. The customer would like to know what's the possible reason for…

  • DRV8302: DVDD_UV condition

    Resolved
    Part Number: DRV8302 Hi Experts, DRV8302 outputs nFUALT pin when the fault condition occurs. One of the condistion is DVDD_UV or DVDD undervoltage which is triggered when DVDD undervoltage condition occurs. What is the UVLO voltage for DVDD? Regards, …

  • DRV8302: Will PowerPAD directly affect device operation?

    TI Thinks Resolved
    Part Number: DRV8302 Hi team, Here's an issue from the customer may need your help: If the PowerPAD is not properly connected to GND, would the device be not able to operate normally when EN_gate is pulled high? GH_X and GL_X are always 0 V? Thanks…

  • RE: DRV8302: DRV8302 heats up on giving power, AVDD, GVDD, and buck output are all at 0V.

    Resolved
    The problem was with the EN_GATE pin. When this pin is set to high all the voltages GVDD, AVDD, and PVDD appear, although EN_GATE pin is only responsible for enabling the gate of driver and current shunt amplifier. Thanks.

  • DRV8302: BLDC Motor Sensorless drive

    TI Thinks Resolved
    Part Number: DRV8302 Other Parts Discussed in Thread: DRV832X I am using a DRV8302 to drive a BLDC motor. I would like to run it in sensor less mode. I have configured the PWM mode as 3 PWM. I am feeding 3 timer outputs from MCU to the DRV8302 three input…

  • DRV8302: SL_x Low Side MOSFET Source Connection Alternative Use

    TI Thinks Resolved
    Part Number: DRV8302 Hi, Good Day. I have a customer who is working with DRV8302. Please see below his query for your reference. Thank you very much. I'm using the DRV8302DCAR to drive FETs in a motor controller. My motors require 5-10Amps, and the DRV8302…

  • RE: DRV8302: Overcurrent protection overly sensitive

    Hi Elizabeth, I finally had some time to run bench testing with DRV8301/DRV8302 in regards to seeing nFAULT behavior occur without much explanation. Going back to the original issue: Andrea Chung said: I am using the DRV8302 to run a BLDC motor using field…
