  • DRV8235: Driving Multiple motors using single DRV8235 motor driver

    Part Number: DRV8235 Tool/software: Hi, The requirement is to drive two or three DC motors using a single DRV8235 motor driver, where the motor driver is controlled by an MCU. So, I need some ideas to switch between the motors using a single driver. Given…

  • UCC24624: Increased FET loss due to early turn-off

    TI Thinks Resolved
    Part Number: UCC24624 Tool/software: Hi, We are currently using the UCC24624 in an LLC resonant converter and are facing a problem where the SR MOSFET gate turns OFF before the drain current reaches zero. This results in extended body diode conduction…

  • BQ25730: Motor drive issues

    TI Thinks Resolved
    Part Number: BQ25730 Tool/software: I am attempting to drive a motor with VSYS. The motor inrush on startup is about 6A. When VBAT is depleted or not connected, VSYS droops significantly and takes out my motor drive circuitry. In addition to the recommended…

  • TIDA-010054: Clarification on Gate Drive Loss Equation in TIDA-DAB-010054

    Part Number: TIDA-010054 Tool/software: Hello TI Team, I’m reviewing the reference design TIDA-DAB-010054 and noticed that the gate drive loss is calculated using the formula: Pgate=2⋅Qg⋅(VDD−VEE)⋅fsw P g a t e ​ = 2 ⋅ Q g ​ ⋅ ( V DD ​ − V EE ​ )…

  • DRV2605LEVM-MD: LRA Motor drive ISSUE

    Part Number: DRV2605LEVM-MD Other Parts Discussed in Thread: DRV2605L Tool/software: I am facing some complexity while testing the LRA motor with the DRV2605LEVM-MD driver board. When I connect the LRA motor to the OUT5–OUT8 port and perform the test…

  • CSD95379Q3M: SYNC-BUCK-FET-LOSS-CALC doesn't work

    TI Thinks Resolved
    Part Number: CSD95379Q3M Hi Team, We've been trying to use the SYNC-BUCK-FET-LOSS-CALC to calculate the losses of CSD95379Q3M. It seems like every time I press any of the '--> --> CLICK HERE <-- <--' buttons a new selection windows starts to open…

  • RE: BQ76930: DSG fet burnout and 1V gate drive

    Hi Arelis, It has been a really long time. Really hoping to get a response from your end.
