BQ25619: PMID_GOOD Behavior During Boost Mode Operation

Part Number: BQ25619

Hi,

I am looking into the PMID_GOOD operation during boost mode OCP. When I(SYS_OCP_Q4) reached, would PMID_GOOD latched at low following the stop of boost mode, or back to high after boost mode stopped?

Best Regards,

Peiheng.

    Peiheng,

    Referring to 8.3.8.4 PMID Voltage Indicator (PMID_GOOD), Once PMID voltage is out of this range, PMID_GOOD goes LOW to disconnect the accessory device from PMID. During boost mode, all the conditions to exit boost mode will drive PMID_GOOD from HIGH to LOW, including boost mode disable in register, ACOV, TS fault, battery depleted (VBAT_DPL), BATFET over-current, (ISYS_OCP_Q4), etc.

    Thanks,

    Ning.
