LTC4365 FAULT Question

Hi,

Looking at the block diagram of the LTC4365 datasheet (page 8), the Fault output is an Open Drain N-MOS. How can it be activated when the IC is out of UV range or totally turned off?

regards,

  • Hello Gaston,

    as this output is active low:

    The function is available as long as the LTC4365 has enough voltage level at its VIN pin(>2.5V). Under this condition the part can actively drive the FET inside and pull low if necessary

    Vin below (configured) UV threshold will not stop the IC from working, as long as VIN is above 2.5V.

    Does this answer your questions?
