BQ25790: Will VBAT_OVP_MASK=1 influence VBAT_OVP function?

Part Number: BQ25790

Hi team,

Could you explain the function of VBAT_OVP_MASK? What is the meaning of "INT", interrupt? 

If I set VBAT_OVP_MASK=1, when VBAT OVP is triggered, will Charger stop charging?

Thanks and look forward to your reply!

    HI Kailun,

    The INT output generates a 128us pulse for any status charge or fault bit change in registers 0x1B-0x27.  The intent is for the host processor to know that something has changed and investigate further.  If certain status or fault changes are not a concern, the mask bits can prevent that status or fault bit change from generating an INT pulse.

    Regards,

    Jeff
