Part Number: BQ24123 Hi,
I'm designing battery stand-alone charger for removable Li-ION battery (single cell).
my questions:
1. Am I understood correctly that the BQ24123 has internal pull-down on pin 13 (CELLS), so I can leave this pin floated?
…
Part Number: BQ24123 Other Parts Discussed in Thread: BQ24125 Hello, we are in pre-production with a charger that uses the BQ24123 or BQ24125 (we have two variants of our design to address possible chip shortages).
We have been testing our charger for…
Yes, we have just finally confirmed the same behavior on a second battery. I have filed a more detailed post titled:
BQ24123: Is it possible to adjust Precharge to fast-charge transition voltage threshold (VLOWV)?
Part Number: BQ24123 Our (2S LiPo) battery protection circuit uses two Under-Voltage-Protection (UVP) stages. The first is at single cell voltage 2.3~2.5V and the second is at <2.3V. When the 2nd UVP has been tripped, we have found that the BQ24123 is…
Part Number: BQ24123 Other Parts Discussed in Thread: BQ25798 Dear Sir/Madam,
My Industrial project old design is using BQ24123. but now there are some design change which change to 2 cell, the battery pack is 7.4V 2300mAH.

Part Number: BQ24123 Other Parts Discussed in Thread: BQ24125 Hi Team,
Please help to understand if BQ24123 can charge 3-Cell Li-Ion And Li-Polymer.
1st page of the datasheet says so: "Suitable For 1-, 2-, or 3-Cell Li-Ion And Li-Polymer", however the…
Part Number: BQ24123 Hello,
I have made a circuit design for charging 2-serial connected Li-Ion batteries through USB 5V input with overcharge protection. Could you check the design?
Thanks
