  • UCC20520: UCC20520

    Resolved
    Part Number: UCC20520 It seems that if the disable input has fast transitions, sometimes both outputs go high, which of course causes a short-circuit.

  • UCC20520: hardware issus

    Part Number: UCC20520 Tool/software: HI TI expert， Customers use the UCC20520 device, as the mos current size changes, the delay varies between 800-900ns, the larger the current, the longer the delay. Oscilloscope waveform primary waveform - green…

  • UCC20520: The programmable dead time is not working.

    Part Number: UCC20520 Tool/software: We are using the UCC20520 with a 100K dead time resistor and 2400pF capacitor in parallel. The chip still does not give us any dead time. We have tried it with a 205K resistor also with no change. Any ideas on what…

  • UCC20520: UCC20520 isolated driver for 15 phase inverter

    TI Thinks Resolved
    Part Number: UCC20520 Hi, I am using UCC20520 isolated driver for 15 phase inverter. So I am wondering if I can design each driver (15 driver pcb) with its own supply and its input filter or use a power managment board able to provide filtered 12V…

  • UCC20520: Is there an internal pull down resistance from the gate to source?

    Resolved
    Part Number: UCC20520 Hi team, My customer has a question on the UCC20520.. Is there an internal pull down resistance from gate to source? From looking at the datasheet, it appears not. But if not, what kind of leakage currents can they expect between…

  • UCC20520: For Analog voltage amplification

    TI Thinks Resolved
    Part Number: UCC20520 We have an old module with SI8231 for AC voltage stepup (Similar to Class D amplifier) I have checked and found both the ICs pin compatible. Advantage of using UCC20520 would be having simulation model available to avoid a spin…
