What is the ICCQ of the fuel gauge if the CE is de-asserted and the FG is in shut down?

Section 7.5 doesn't specify the CE pin status.

Nick,

When the CE pin is low the gauge is effectively off. There should be no draw from the gauge outside of possible leakage. CE pin disconnects the LDO and the regulator.

Thanks,
