INTVCC_UVLO value of LT8645S

Hi,

I confirmed the INTVCC_UVLO from the block diagram.
But I can not confirmed value of INTVCC_UVLO.
Let me know if you know this value.

Best regards

  • Hi kshigemori281,

    INTVCC UVLO is an input to the OR gate for the PG pin but this signal can't be controlled. What is the reason this is important in your application? INTVCC is the output for the internal 3.4V regulator and this pin should not be loaded with external circuitry.

  • Hi,

    I have trouble Both LT8620 and LT8645S. I also confirmed similar problem.
    First of all , I confirmed INTVCC waveform of LT8620 that reached UVLO when It's reverse voltage.
    Second of all, I confirmed value of INTVCC UVLO with datasheet of LT8620. Therefor I confirmed value of LT8645S. However I couldn't confirm this.
