BQ24800 has similar battery quiescent current as BQ24780S, however it has other improved feature, such as 300kHz/400kHz switching frequency, which helps with the min AC voltage as close as 12.6V.
Hi Jun,
What's the customers end application? We have BQ24800 or BQ24725A our latest SMBus chargers the customer can use.Can you please follow-up via Email to discuss more on customer system requirement?
Thank you.
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ24800 , BQ24773 , Hi,
I have this BQ40Z50-R2 as a battery fuel gauge in the battery pack, and i have a battery charging IC BQ24773 or BQ24800. Both the fuel gauge and charging IC are communicated…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ25790 , BQ24725A , BQ24800 , BQ40Z50 , BQ24725 Hi,
Based on the BQ40Z50-R2 datasheet, this support JEITA charging algorithms. I am a bit confused, what is the different between the JEITA in…
Hi Steve,
Thank you for reaching out!
I suggest either the BQ25720 or the BQ24800 . They do not have the integrated FETs, but are both SMBus-controlled chargers.
Please let me know if you have additional questions/concerns.
Best Regards,

Hi Noah,
1. The current reading will be doubled with 5 mohm. Set RSNS_RAC and RSNS_RSR=5mohm is good for the PSYS calculation, but it does not affect the current reading scale up. More details, see below.

Hello Zhang,
What is the purpose of Q35? I recommend refering to our schematic checklist: BQ24800_BQ24780s Layout Guideline (4).pdf

Hi Saravanan,
See below post on the current sense. You can use BQ25710 for 140W power. BQ25720 has slightly better efficiency through.

Hi Steve,
thank you for your time and great answers. However, some things are still a little unclear to me:
>> C12, C13 and R7 form a soft start circuit for the Q1 and Q2 (AKA ACFET and RBFET) If you remove the soft start circuit, the FETs will turn…
