Part Number: BQ24253

Is the safety timer fixed for 6 hours? Can I change it and how? Is there timeout protection for pre-charge?

Hi,

I misread the part number. The standalone version does not allow for changing the safety timer. The timer is reset with /CE pin or HiZ toggle.

Hi Jeff,

Thank you for reply. Does the safety timer only contain the process of CC and CV? Then what is the safety time for trickle and pre-charge?

HI Donghang,

There is one timer for all charge stages.
