BQ20Z75 AFE.State_CTL

Hello again,

Does anyone know what the definition of the BQ20Z75 AFE.State_CTL flags are in GGEV software? I can't find a valid definition anywhere.

Regards

    Simon,

    You can find information on the AFE.State_CTL register in the bq29330 Datasheet. Search for State_Control.

    Hi Tom,

    Thanks for pointing me there, I found the register in the bq29330 datasheet as you suggested.

    It seems for the bq20z75 there is some assumption that one knows the history of the chips, but as a newbie I had no idea where to find that information. IMHO it really should be included in the bq20z75 datasheets somewhere.

    Cheers

    Hi Tom,

     I think bq29330 datasheet isn't  definition AFE.State_CTL

    The STATE_CTL register controls the outputs of the bq29330 and can be used to clear certain states.
    STATE_CONTROL b0 (SLEEP): This bit is used to enter the sleep power mode.
    0 = bq29330 exits sleep mode (default).
    1 = bq29330 enters the sleep mode.
    STATE_CONTROL b1 (SHIP): This bit is used to enter the ship power mode when Pack supply voltage is not
    applied.
    0 = bq29330 is in normal mode (default).
    1 = bq29330 enters ship mode when pack voltage is removed.
    STATE_CONTROL b2 (WDDIS): This bit is used to enable the watchdog timer.
    0 = Watchdog timer is enabled (default).
    1 = Watchdog timer is disabled.
    STATE_CONTROL b3 (WDRST): This bit is used to enable the reset for GC, when watchdog timer is active.
    0 = Reset output is disabled, when watchdog timer is active (default).
    1 = 2 Times reset output is enabled, when watchdog timer is active.
    STATE_CONTROL b4 (RSNS): This bit sets the OL, SCC, and SCD thresholds into a range suitable for a low
    sense resistor value by dividing the OLV, SCCV, and SCDV selected voltage thresholds by 2.
    0 = Current protection voltage threshold as programmed (default)
    1 = Current protection voltage thresholds divided by 2 as programmed
    STATE_CONTROL b6..7 (0): These bits are not used and should be set to 0.
    20

    I find information on the AFE.State_CTL register in the bq20z60-R1/bq20z65-R1 TRM

    They have different definitions.

    Which one is correct?

    Cheers

    David,

    These two registers do not have different definitions. The bq29330 is used in the bq20z65 and all of the features may not be used.
