  • DRV8353RS-EVM: DRV8353RS EVM Board not working

    Part Number: DRV8353RS-EVM Other Parts Discussed in Thread: DRV8301 We are using the DRV8353RS EVM and the board is not working properly. We have trouble with the gate not switching properly. The gate driving output of the board is at too low of a voltage…

  • DRV8353RS-EVM: Using DRV8353rs-evm with STM Nucleo H755ziq eval board.

    Part Number: DRV8353RS-EVM I am a beginner and I have been trying to build a robot where my Nucleo H755zi-q will act as the motor controller. After research on chatgpt I got my hands on the DRV8353rs-evm to power a 3 phase 120 Degree Hall sensor based…

  • DRV8353RS-EVM: Questions about DRV8353RS 3x PWM mode (INLx control)

    TI Thinks Resolved
    Part Number: DRV8353RS-EVM Dear TI Support, I am using the DRV8353RS in 3x PWM mode for sensored 6‑step BLDC control and I have two clarification questions about the INHx / INLx inputs: In 3x PWM mode, should the INLx pins (INLA, INLB, INLC…
