Part Number: BQ24618 Hi,
This is related to my previous question regarding BQ24618 as I have been looking into the design again.
The BQ24618 circuit is part of a larger charger design which has had two versions. The circuit I shared previously is almost identical…
Hi Vaisakh,
I will close out this thread as I have not received an update.
Feel free to open a new thread if you have further questions.

Part Number: BQ24618 Other Parts Discussed in Thread: BQ24610 I would like to use the BQ24618 as a charging circuit for a 6V 7AH lead-acid battery. Requirement 800mA charging current. 1.46A system current. End of charge voltage 6.9V. Input voltage 12V…
Hi Boris,
After doing more analysis on the waveform above, it looks like the REGN voltage on the failed unit is higher than we expect (circled in red).
This voltage should be regulated at ~6V (similar to what is seen in the normal waveform).
It seems…
Part Number: BQ24618 Hi TI Teams,
We plan to use the BQ24618 for 6-cells battery charging, and the voltage of the battery are fully charged at around 25V. From the datasheet we can learned that the BQ24618 is a buck battery charging IC, so how can we fully…
Part Number: BQ24618 Good morning,
We have designed a charger based on the BQ24618 that has been working fine for many years without issues. It is a 4S Lion charger that sources up to 2.5A.
Lately, we have made a new revision increasing the power output…
Part Number: BQ24618 I designed a new board with a BQ24618, basically using the circuit in the datasheet, for 2 series LiIon cells making a 7.4V nominal 8.4V max battery.
It seems to be charging as expected, then all of a sudden it suspends/ends charging…
Part Number: BQ24618 Hello team,
According to datasheet 8.3.2, I_charge could be fixed by R_sr.
If the customer wants to design adjustable I_charge, do they need to add an external circuit such as switches?
Do you have any experience about this or reference…
Part Number: BQ24618 Other Parts Discussed in Thread: BQ24630 ,
Hi,
First of all, I have been checking the forums for similar issues, especially on the bq24630 but don't think they are completely similar to my case.
We have been designing chargers…
Part Number: BQ24618 Other Parts Discussed in Thread: BQ24617 , BQ24610 BQ24618に入力24V/2.1AのACアダプタを使用する充電回路基板を設計していますが、フル充電検出電圧を23.86に設定すると、フル充電検出電圧付近で充電が停止します。 充電電圧を23.37Vに設定し、バッテリを23.56Vに充電すると、瞬時に停電が発生し、電圧が23.35Vに低下し、CVモードで充電が再開されます。 原因究明の方法を教えてください。
