Part Number: BQ24630 Tool/software: Hello,
I have trouble with the charging process of my design. I used the BQ24630 chip the schematic looks like this:
My charging curve is not as I expected continously. It stops after every 1min24sec and starts again…
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…

The customer design with BQ24630 to charge BQ78350+BQ76920. They found it is easy to burn the BQ24630 and its peripheral components.
BQ76920+BQ78350 battery management board is connected…
Hi Michael,
We tested the updated board with the FETs that have much lower gate capacitance and just like magic, the IC power consumption dropped to normal levels!
This was a learning experience. I just wish we did not spend a month finding this simple…
Part Number: BQ24630 Hi
My customer designed the schematic with BQ24630, found the output voltage unstable and can't charge.
Attached the schematic for your reference.
When the adapter is powered on, the voltage at VBAT has been jumping, and the…
