    BQ27425-G1, Is the CE Chip enable just for the LDO, or the whole device?

    If I set the Chip Enable (CE) Low on the BQ27425-G1, will the rest of the device function? Does this just disable the LDO? Does it put the whole device into power saving mode?

    RE: BAT_DET and learning cycle

    Why did you set OpConfig to 0x5EFE? RSVD0 must be 0 and RSVD1 must be 1 for proper operation. If you have and external pull-up on BIN then you can set BI_PU_EN to 0. See Table 8 in www.ti.com/.../bq27425-g1.pdf . Please change this to 0x09FE
