LT8610's SYNC pin

Hello,

Is it possible to input the pulse signal (0V / 3.3V) to the SYNC pin before powering on LT8610 (VCC = 0V)?

The maximum rating for the SYNC pin is 6V.

Best regards,



How many amperes does the current flow when 3.3V is input to the SYNC pin without powering on LT8610(VCC=0V)?

    Hello,

    Thanks for application of LT8610.

    Yes, it should be good to have the input pulse signal 0V/3.3V to the SYNC before power-on.

    The SYNC pin has a max rating voltage of 6V, and it is strongly recommended to not exceed this rating voltage.

    In this case, the typical Vin quiescent current is 1uA.

    Best regards,

    Andrew
