  • ISO5452: Can I replace ISO5452 with ISO5852?

    TI Thinks Resolved
    Part Number: ISO5452 Other Parts Discussed in Thread: ISO5852S I am using ISO5452 driver in solar inverter (three phase) with DC bus ranging from 200V to 800V with switching frequency 4kHz. I bought ISO5852 instead of ISO5452 due to component non-availability…

  • ISO5452: Driving two IGBTs in parallel

    TI Thinks Resolved
    Part Number: ISO5452 Can I drive two IGBTs in parallel using single driver IC? If yes, What is the recommended circuit connection with respect to OUTH, OUTL, CLAMP pins?

  • ISO5452: DESAT during start up

    Resolved
    Part Number: ISO5452 Hi team Our customer is using ISO5452 as IGBT driver in servo, but we found that there is no clarification of DESAT during start up(VCC2 UVLO) in our datasheet, what would happen if IGBT is short already when starting up? Does DESAT…

  • ISO5452: Is there any concern with 9V DESAT threshold voltage?

    Resolved
    Part Number: ISO5452 Customer was concerned about 9V of the DESAT threshold voltage of ISO5452, since they are afraid the short circuit current might go up a lot until the voltage reaches up to 9V. I believed it should be okay if using a small capacitor…

  • ISO5452: Question for ISO5452 DESAT pin behavior

    TI Thinks Resolved
    Part Number: ISO5452 Hi Team, Our customer is evaluating the ISO5452 in their application, during their test, they found that when there is no HV voltage applied on the IGBTs, we will still see the FLT triggered to low. They want to know if this is the…
