IC LT8584 - what pin (DIN or DCHRG) to use to get low quiescent current in simple mode ?

I plan to use IC LT8584 in simple mode. There are two possibilities how to control (enable) switching. I need to get low quiescent current when switching is off.
On datasheet  on page 3. is wriiten that low quiescent current is reachable when Din = OUT ??  What it means OUT - just let it floating?
In simple mode there can be used either Din or DCHRG pin to control switching. Does both possibilities allows to reach low quiescent current ( few nA) or I should use Din pin for switching control?

    Simple mode is controlled by both DCHRG and DIN pin.    The balancer is on when DIN is low (Ground) and DCHRG is high (VIN).  Any other combination will put the part in low IQ state (<20nA).    Thus, this allows either logic high enable via DCHRGE or logic low enable via DIN.   DIN is referenced to the OUT pin; and if DIN = OUT, the part will be in shutdown.   DIN may be floated to disable, but most user will drive DIN all the way to VIN, which is recommended.
