Part Number: BQ24630 Other Parts Discussed in Thread: BQ24620 , Tool/software: I am designing a standalone battery charger for 8 LifePo4 6000mAH Cells in parallel. I do not need any other features. The BQ24620 does not work because the safety timer is…
Part Number: BQ24630 Tool/software: I have used this charger on a multiple other packs to charge a 3s 3p LiFePO pack. The circuit design is very similar to the datasheet shown below:
Only one pack seems to have this problem, but replacing the charger…
Part Number: BQ24630 Tool/software: Hi team,
We are trying to charge a 1500mAh 4S LiFePO4 battery using the BQ24630. When we apply 24V, whether the battery pack is connected or not, the Vref and Vregn voltages do not appear. The VCC voltage is 24V,…
Part Number: BQ24630 Tool/software: Hi,
From what i can see the device is behaving as it should but Im a bit confused with the STAT1 and STAT2 pins.
I have them connected to an MCU and to a LED shown in the image below. Ive noticed that it says LED…

Part Number: BQ24630 Hi Team,
When charging is completed, there will be an abnormal state of charging and discharging flashing. Attached is the charge and discharge log. It includes the charge and discharge logs of normal machines and NG machines. …
Part Number: BQ24630 Hi team,
Throughout the BQ24630 datasheet, there is use of the term VRECH. It is never defined, but it's obviously close to Vrechg.
Is VRECH it's own term? If so, how is it defined/calculated?
If VRECH = Vrechg, can we get some…
Part Number: BQ24630 Hi,
We have a PCB that uses BQ24630 to charge a LiFePO4 pack.
On our first board all was ok. BQ24630 was taking from VCC about 9.1mA when charging and 5mA when battery was absent.
When we assembled a second board from the same…
