Part Number: BQ24780S Hi,
We use the BQ24780S for the bettery charger, and now, the output voltage is closed after power on 3minutes,
The register set as below, please advise if there are any error, thanks.
Part Number: BQ24780S Other Parts Discussed in Thread: BQ24800 Hi Expert,
Do we have any concern if we use BQ24781R as the 2nd source for BQ24780S?
Could you provide a comparison table for BQ24780S and BQ24781R?
Hi Lumina,
I will close this thread since I have not received any updates.
Please feel free to open a new thread if you have further questions or concerns.
Best Regards,

Part Number: BQ24780S Hi,
We consider to use the BQ24780S for the battery charger controller, the input voltage is 8-24V and the charger current is more than 5A, the output voltage is
now, baesd on the reference design, the V(IADP), V(IDCHG), V(PMON) and…

We have some question about the application of BQ24780S when the battery pack does not have a BATPRES output pin. We have found a post about battery packs without BATPRES…
Part Number: BQ24780S Dear e2e support,
On the EVM schematic, we recommend a 6.8ohm resistor (R19) between BSTS and PHASE.
Is there a rough calculation on the power dissipation of it? Can we use a 1/16W 0604 resistor?
Regards,
Part Number: BQ24780S Hi Expert,
The maximum battery charging voltage is 13.05V.
What is the minimum B+ voltage you recommend of BQ24780S for battery charging to work normally?
Are you concerned that B+ is 15V?
