  • ISO5451: IN+ hysteresis voltage?

    Resolved
    Part Number: ISO5451 Team e2e, I am simulating ISO5451 model in TINA TI. Acc to the datasheet, the input hysteresis voltage at IN+ is typically 0.15 * Vcc1 --> In my test case, Vcc1 = 5V, hence hysteresis V = 0.75V, which means that the switching…
