Hi,
I have doubt on BQ25708 Battery charge voltage configuration .
In my case Battery is single cell and 12V .
need battery charge voltage as 12V for single cell.
Note1:-
Here mentioned 1-cell configuration battery voltage is 5V.
Note 2:-
As per this statement can we configure battery charge voltage as 12V or not?
Kindly advise how to configure battery charge voltage (12V) for single cell ?
Thanks,
Muthuvel K
Hi, Muthuvel,
The datasheet refers to Li-ion battery when describing the cell settings, however, it does not forbid this part using in the multi-chemistry batteries.
NiMH battery cell voltage is 1.2V, Li-ion battery cell voltage is 4V, some other battery cell voltage is as high as 12V. We can use an equivalent cell settings as a starting point, then modify the register values to suit the need.
I would suggest you picking 3 cell Li-ion battery as equivalent to 1 cell of 12V battery.

Hi Tiger Zhou,
Subject: Request for Battery Charger Recommendation.
We are looking for a battery charger with the following specifications:
Battery charge voltage: 12V
Battery charge current: 3A
The type of battery to be used will be decided by the customer. As of now, we only have the charging voltage requirement of 12V. The battery charger should
support multiple battery types, including Lead Acid and Li-ion.
Please recommend a suitable charger that meets these criteria.
Kindly advise.
Thanks,

Hi, Muthuvel,
BQ25708 can support your application. Set CELL_BATPRESZ pin at 3.3V which is 55% of REGN.

Hi Tiger Zhou,
Can u confirm BQ25708 is only for li-ion or can be used for multi chemistry like Lead acid battery.
because The type of battery to be used will be decided by the customer.
customer only confirmed charge voltage as 12V.
if customer may uses either lead acid or li-ion battery .
Thanks,

Hi, Muthuvel,
BQ25708 can be used for multi-chemistry batteries. It does not care what type of battery, simply set charge voltage and charge current. It will charge.
