  • TIDA-00778: Anti aliasing filter selecting

    Resolved
    Part Number: TIDA-00778 Hello, In TIDA-00778 design, we can see a anti aliasing filter with cutoff frequency of 15 MHz. The picture below shows this filter: Also, the following picture shows the ADC input impedance model for TMS32028027F. So, I have…

  • RE: LAUNCHXL-F280049C: Cogging rotor no speed control SDK Lab05

    Resolved
    Oddly TI kits using IGBT module ,GAN, NEXFET versus 1/2 bridge UCC27714 (TIDA-00778) seem to have floating charge pump integration over HO boot strap cycles. Perhaps IGBT module (TIDA-00778) simply has reverse voltage leakage (E->C) keeping boot charge…

    Resolved
    Hi Chaitanya, Adding to Kevin's resopnse - Lets call MOSFET current as low side current. Outcome of low side sensing and phase current sensing is similar with following difference: Low side current is dicreate in nature because of switching of low…

  • RE: EK-TM4C1294XL: External GPIO pull downs on PWM pins

    Resolved
    Since your questions are around the design of the TIDA-00778, which uses a TMS320F28027 processor, I will transfer this thread to that group.

  • RE: I need to design single phase 180VDC (2kW) PMDC motor speed control driver

    Hello Maynard, Thank you for checking with us. I assume you refer to a single-phase brushed PMDC motor and not a single-phase brushless DC motor? We don’t have an integrated solution for >60V brushed DC motors and I’ll list below what we have.…

  • UCC27714: Input pull down

    Resolved
    Part Number: UCC27714 Other Parts Discussed in Thread: TIDA-00778 Why would it be necessary to add external pull down resistors on GPIO pins when the gate driver inputs have 400k pull downs? Do parallel external pull downs (10k/100k) change SNR of the…
