Hello Anoop,
Do you see this issue if you increase the input voltage?
Can you provide a scope capture of VCC, SRN, Sysstem voltage, ACDRV, measure close to the pins.
Best Regards,
Christian
Part Number: BQ24618 Other Parts Discussed in Thread: BQ24610 Tool/software: Hello, I made two series charger with BQ24618 and not working neither version for type 5S, Uin=24V.
Output voltage is still 1,8V on pin PH.
I checked everything and I don't know…
Part Number: BQ24610 Other Parts Discussed in Thread: BQ24618 Tool/software: I am currently designing and testing a custom board using the BQ24610. I am facing an issue with the input voltage range and am looking for a component with a wider input voltage…
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.

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…
