Mistake in BQ25505 Data sheet? ship mode

Hi,

Under Section 6.6 Typical Characteristic, Table 1. It says

!EN = VBAT_SEC (Active Mode) next to Figure 8

!EN = VBAT_SEC (Ship Mode) next to Figure 10

How can it be in both modes when !EN is tied to VBAT_SEC?

/EN is an active low digital programming input for enabling/disabling the IC. Connect to GND to enable the IC.

Please meke sure you are looking at the latest revision that is on our website.

Anyway, from the datasheet link you provided, i do not see the description in your post. Figure 8 has /EN = GND as highlighted shows the IC in main boost charger active mode, and figure 9 has /EN = VBAT_SEC which puts the part into ship mode. Figure 10 does not shows the leakage current on VBAT_PRI which does not related to ship mode.

This is what I'm looking at - from Ti's website.

I apologize for the confusion. /EN = VBAT_SEC puts the IC to ship mode. /EN = GND puts the IC to active mode. We will correct the datasheet in our next revision.
