UCC21520: UVLO for one channel will turn off both channel?

Part Number: UCC21520

Hi,

I want to clarify the logic of the device.

If only VDDA falls below UVLO threshold, both OUTA and OUTB will be held low, right?

  • Hi, Howard,

    No, on the output side, chan A and B are independent of each other.

    So, if VDDA goes below UVLO, then OUTA will be pulled low, but OUTB will continue to follow INB.
