BQ24195L: Shipping Current

Part Number: BQ24195L

In an effort to reduce the quiescent power draw from the battery we have shut down the MCU, but the BQ24195L is still pulling about 20-25uA.

How low is this expected to go if we implement the following per the data sheet?

    Hi Gary,
    There are several different levels sleep the chip can be in.
    Looking at section 7.5 of the datasheet (snapshot below), is it possible you're in either of the "high-Z mode" states?
    Is V_bus less than V_uvlo for lowest Iq?
    Thank you, Keith
