BQ25898D: about IDPM_STAT

Part Number: BQ25898D

hello,

IDPM_STAT of REG13 is described as IINDPM Status.
As shown in the following data sheet excerpt, the limiting current varies depending on the ICO_EN register setting.
Is IDPM_STAT set to 1 as follows?
When ICO_EN is 1, IDPM_STAT is 1 when the current is limited by IDPM_LIM.
When ICO_EN = 0, IDPM_STAT is 1 when the current is limited by IINLIM.

Data sheet excerpt
The actual input current limit used by the Dynamic Power Management is reported in IDPM_LIM register while Input Current Optimizer is enabled (ICO_EN = 1) or set by IINLIM register when the algorithm is disabled (ICO_EN = 0).

best regards

    Hi,

    1)During DPM mode, the status register bits VDPM_STAT (VINDPM) and/or IDPM_STAT (IINDPM) is/are set high.

    2)The actual input current limit used by the Dynamic Power Management is reported in IDPM_LIM register while Input Current Optimizer is enabled (ICO_EN = 1) or set by IINLIM register when the algorithm is disabled (ICO_EN = 0). In addition, the current limit is clamped by ILIM pin unless EN_ILIM bit is 0 to disable ILIM pin function.

    Thanks,

    Ning.
