  • UCC27533: Three Phase Inverter Driver Circuit using ISO7710 and UCC27533

    TI Thinks Resolved
    Part Number: UCC27533 Hi, I am referring to Application Report SLUA669A. I have a three phase inverter using a setup similar to the application note. The PWM inputs go through a ISO7710f isolator and then power MOSFET's through a UCC27533 driver, unlike…

  • UCC27533: what's the 'x' meaning in true table?

    Resolved
    Part Number: UCC27533 Other Parts Discussed in Thread: UCC27536 Hi, in datasheet true table, there are 'float' and 'x'. i think float represent 'leave this pin unconnected', right? what's the 'x' meaning?

  • UCC27533: Only works the first time

    Part Number: UCC27533 Hello, I am having a problem with this driver. I wanted to do a simple test so I soldered it on a perfboard and connected it to Arduino. I tried with 100nF and 1uF capacitors on the power supply but the results are always the same…

  • UCC27533: Bypass capacitor value

    TI Thinks Resolved
    Part Number: UCC27533 Hello, We would like to know the recommended bypass capacitor value. Is it 0.1uF ceramic capacitor enough for this? Approximately in how far the bypass capacitor is ok for "as close as possible"? Better than close 2 or 3mm from VCC…

  • UCC27533: The interface circuit design between UCC2753X and CPLD, when the UCC2753X GND pin is negative.

    Resolved
    Part Number: UCC27533 I am designing a gate driver for sic mosfet module using the ucc2753x. The sic mosfet is powered by a positive and a negative bias. That means the GND pin must be negative, however all the input signals of ucc2753x are reference…

  • UCC27533: UCC27533 Glitch On Start-Up

    Part Number: UCC27533 I have a customer seeing the following issue with the UCC27533: My circuit is pretty simple. VDD and IN+ are tied together. IN- and GND are tied together. A decoupling capacitor of 100n is put right across VDD and GND. My application…

  • UCC27524: what's the continuous and pulse negative voltage value of UCC27524?, INx and ENx pin

    TI Thinks Resolved
    Part Number: UCC27524 Other Parts Discussed in Thread: UCC27533 , Hi what's the continuous and pulse negative voltage value of UCC27524?, INx and ENx pin in datasheet, it show -0.3V, is it continuous value or pulse value? in UCC27533 datasheet, it…

  • RE: Buck Regulator + Gate Driver in place of HB-LLC (UCC256301) topology

    Rajkumar You don't need a half bridge driver, you can use UCC25706 with a low side gate driver such as UCC27533. You could also use one of our controllers that integrate the gate driver like UCC28C43. Design support tools for all of these devices are…
