  • RE: UCC23513: Dual channel version of UCC23513

    Resolved
    Dear Dapkus, In the data sheet of UCC21551, I see there is a capacitor C BOOT and C VDD that is recommended. As my requirement is only to shift the voltages (3.3V to 15V), is it mandatory to use those capacitors? Actually there are separate gate drivers…

  • UCC5350-Q1: The Vgs waveform of high side SiC MosFET using UCC5350 by bootstrap power supply in motor control application

    TI Thinks Resolved
    Part Number: UCC5350-Q1 Other Parts Discussed in Thread: UCC5350 , UCC21551 Hi I'm testing UCC5350 for SiC driver in PMSM control application(600VDC input). I use bootstrap method to give the high side UCC5350 Power supply. The waveform of the Vgs is…
