  • DRV8353: DRV8353S: SEL_LVL Test

    Part Number: DRV8353 Dear TI Team, I am currently debugging a SEN_LVL fault issue on our motor driver design and would like to get your support for clarification. During operation, a SEN_LVL fault is intermittently triggered, as observed via SPI status…

  • DRV8353: DRV8353: using external amplifier to overcurrent protection

    Part Number: DRV8353 Hello, I am designing a 3-phase BLDC motor controller using the DRV8353. I want to implement a custom overcurrent protection (OCP) using an external non-inverting amplifier, but I am concerned about the DRV8353 operation. [The Setup…

  • DRV8353: The DRV8353 chip may be damaged.

    TI Thinks Resolved
    Part Number: DRV8353 Hello, TI engineers. We are using the DRV8353SRTAR in our BLDC motor projects. In a previous application, I connected VM and VCP through a 1µF 35V capacitor, and everything worked normally without any issues. Now, in a new project…

  • DRV8353: DRV8353S — GDUV fault at 160kHz with SIDR5802EP, charge pump capacity limit and slow Vgs_HS rise

    TI Thinks Resolved
    Part Number: DRV8353 Hi, I am designing a 3-phase BLDC motor driver using the DRV8353S in 6x PWM mode. My system parameters are : Supply voltage : 30V to 60V (VDRAIN) Switching frequency : 160kHz MOSFETs : 6× SIDR5802EP (Qg_typ = 37.3nC, Qg_max…

  • DRV8353: DRV8353s dead-time compensation disappeared

    Part Number: DRV8353 Other Parts Discussed in Thread: CSD19537Q3 , Dear Team, We have developed a motor driver using drv8353SR. we produced some boards test is good! Then we produced second batch( No design changes),when we test no motor load. the…

  • DRV8353: DRV8353 – Gate waveform distortion and nFAULT triggered at high current during direction change

    Part Number: DRV8353 Device Information Device: DRV8353HRTAT Application: 3-phase inverter / rotary motor drive Motor current: up to ~40 A Issue Description We are experiencing an issue with gate waveform distortion and nFAULT…

  • DRV8353: DRV8353S hardware fault Issue(related SPI and Pump capacitor)

    Part Number: DRV8353 When reading through SPI, I observe the following fault conditions: Fault Status 1: 0x0200 → VDS_OCP VGS Status 2: 0x0040 → GDUV (Gate-Drive Undervoltage) When I apply the EN (Enable) signal, the DRV8353 heats up…

  • DRV8353: DRV8353: When initializing, the GDUV error occurred.

    Part Number: DRV8353 hello,I have configured several registers of the drv8353sr as follows: Gate Drive HS Register---0x300 Gate Drive LS Register---0x700 when I enable the drv8353sr and read the fault register 1 and the fault register 2. the register…

  • DRV8353: DRV8353 GDF fault--What is the threshold of VGS voltage?

    Resolved
    Part Number: DRV8353 Tool/software: In datasheet of DRV8353, "If at the end of the tDRIVE period the VGS voltage has not reached the correct threshold the gate driver will report a fault. To make sure that a false fault is not detected, a tDRIVE time…
